What Size Are Amazon FBA Labels — Guide & Templates

Published: May 26, 2026 | Last updated: May 26, 2026

What size are Amazon FBA labels? Most sellers use two primary sizes: 1" x 2-5/8" for FNSKU or product barcode labels, and 4" x 6" for carton and shipping labels. The smaller sticker usually matches Avery 5160-style sheets for item labeling, while the 4x6 Amazon label format is standard for box labels printed on thermal printers. If you send inventory to FBA, using the right label size for FBA products matters because scan failures can delay receiving, create relabel fees, or trigger shipment problems.

This guide explains standard Amazon FBA label size options, the difference between FNSKU and shipping labels, the best templates and printers, print settings, placement rules, cost trade-offs, and a practical QA process you can use before every shipment.

Quick reference: Standard Amazon FBA label sizes

What is an Amazon FBA label?

Amazon FBA label size depends on the label type. A product label is usually an FNSKU barcode sticker placed on the item or unit packaging. A shipment label is the larger carton or carrier label placed on the outside of a box going to an Amazon fulfillment center.

Product-level labels (FNSKU), recommended size

For most unit-level labels, the standard FNSKU label size is 1" x 2-5/8", which is the same size used by Avery 5160-style templates. Sellers ask us all the time, “how big are Amazon FBA labels for each product?” This is usually the answer. That size gives enough room for the barcode, FNSKU text, product name, and condition line without shrinking the barcode too much.

In our experience managing Amazon stores, 1" x 2-5/8" works well for most boxed supplements, beauty items, home goods, and standard poly-bagged products. Small products can use smaller labels in some cases, but the barcode still needs to scan cleanly and remain readable after storage, handling, and inbound receiving.

Carton and carrier shipping labels, 4" x 6"

The standard Amazon shipping label size for cartons is 4" x 6". This format is common because thermal printers like Zebra, Rollo, and DYMO can print 4x6 labels quickly and consistently. If you are printing box labels for SPD or LTL prep workflows, 4x6 is the most practical option. Many sellers refer to this simply as the 4x6 Amazon label.

That same size is also common for carrier labels. Using one printer format for FBA box labels and parcel labels reduces setup errors.

Other sizes you may encounter

Amazon barcode label size can vary by product shape and packaging. For very small items, sellers sometimes use labels closer to 1" x 1" or 0.75" x 0.5", but only when the printed barcode remains scannable. Apparel often uses sticker placement on a poly bag or hang tag area rather than directly on fabric packaging. For oversized units, a larger printable FBA label size may make sense if the seller wants better visibility during prep and warehouse handling.

Amazon’s official labeling requirements and scannability standards

What Amazon requires on a product label

What is an FNSKU? FNSKU is defined as the Fulfillment Network Stock Keeping Unit, Amazon’s barcode identifier used to track a seller’s inventory inside the FBA network. If your product requires Amazon barcode tracking, each unit needs the right FNSKU label applied in a scannable location.

Amazon states that labels must be readable and placed so associates can scan them during receiving and fulfillment (Amazon Seller Central, Label products and shipping requirements). Amazon also requires sellers to cover existing scannable manufacturer barcodes when the product is being tracked by FNSKU rather than by UPC or EAN. If both codes remain exposed, receiving errors become more likely.

We have seen this issue with clients who sent products with a clean FNSKU on the front and an exposed UPC on the side panel. Amazon sometimes receives the unit against the wrong barcode path, which can create stranded inventory or relabel work.

Barcode quality and scanning best practices

Barcode readability is about more than Amazon label dimensions. Print quality matters just as much. For sheet printing on laser or inkjet, we recommend 300 DPI or better. For thermal printers, 203 DPI is common and often acceptable for 4x6 carton labels, though 300 DPI gives cleaner detail on smaller barcodes. Use black ink only for barcode areas, keep page scaling at 100%, and avoid “fit to page.”

Every barcode needs a quiet zone, which is the blank space around the bars. If text, borders, or package graphics crowd that space, scanners can misread the symbol. Orientation matters too. Put the label on a flat surface, not across a seam or curved edge.

When Amazon allows manufacturer barcodes instead of FNSKU

Some products can use the manufacturer barcode rather than an Amazon FNSKU. Eligibility depends on product category, condition, commingling settings, and the barcode path selected in Seller Central. Brand-registered sellers may have more control, but the product still has to meet Amazon’s requirements for manufacturer barcode use (Amazon Seller Central, 2026).

If you choose manufacturer barcode tracking for eligible SKUs, you may not need to print item labels at all. Still, verify that setup before shipping. A wrong assumption here leads to one of the most expensive receiving mistakes because every unit may need relabeling after arrival.

Templates and file formats: setup for easy printing

Common label templates

The most common Avery label for Amazon FBA is Avery 5160, which gives 30 labels per US Letter sheet at 1" x 2-5/8". Avery 8160 is the same dimensions with a different adhesive and packaging variant. For larger product labels, sellers sometimes use 2" x 4" sheet labels, especially if the item has enough surface area and the warehouse wants easier visual confirmation.

For carton labels, use a dedicated 4" x 6" thermal layout. Zebra-compatible, Eltron-compatible, and generic 4x6 roll templates all serve the same purpose as long as the printer driver is configured correctly.

Seller Central usually offers label outputs in PDF. Some workflows also support PNG or direct thermal formatting, depending on the shipping path and browser behavior. PDF remains the safest option because it preserves exact dimensions if you print at actual size.

How to export the right format from Seller Central

1. Open Manage Inventory or the shipment workflow in Seller Central.
2. Select the SKU or shipment you need to label.
3. Choose Print item labels for FNSKUs or the shipment label option for cartons.
4. Select the correct template, such as 30-up sheet labels or 4x6 thermal.
5. Enter quantity carefully. This is where duplicate or missing labels often start.
6. Download the file in PDF if available.
7. Print one test page before running the full batch.

We recommend naming downloaded files with the shipment ID and date. That simple habit cuts down on mix-ups when several shipments are being packed at once.

Choosing hardware and supplies: printers, label stock, adhesives

Printer types compared

The best printer depends on volume. A low-volume seller can do fine with a laser printer and sheet labels. A warehouse shipping daily should almost always use a thermal setup for 4x6 labels. In our own client work, the biggest jump in speed usually happens when a team stops printing carton labels on standard paper and switches to dedicated roll labels.

Popular options include Zebra GK420d or similar Zebra desktop units, plus Rollo-class printers for small and mid-size operations.

Label materials and adhesives

Permanent adhesive is best for most FBA prep. Removable adhesive can shift or peel in hot trailers, especially on shrink wrap or dusty packaging. Matte labels scan better than glossy labels in most environments because there is less reflection. For glass, coated cartons, and poly bags, use labels that are designed for slick surfaces.

Apparel needs extra care. A strong adhesive sticker placed directly on a delicate box can tear the finish when removed in returns processing. In those cases, a poly bag with the FNSKU on the outside often works better.

Supplies checklist

• 30-up Avery 5160-style sheets for standard FNSKU work
• 4x6 thermal roll labels for carton and shipping labels
• Permanent adhesive stock for boxed goods and poly bags
• Matte face stock for better scan contrast
• Test scanner or smartphone barcode app for QA
• Dry storage area, because humidity can warp sheet labels and weaken adhesive

Print settings and step-by-step printing workflow

Recommended print settings

For sellers asking, “what size are Amazon FBA labels supposed to print at exactly,” the answer is simple: print at the file’s true dimensions with no scaling. Set scale to 100% or Actual Size. Use at least 300 DPI for laser or inkjet. For thermal, 203 to 300 DPI is standard. Keep the barcode in solid black on a white background. Do not print in draft mode.

One practical check is to measure the finished label with a ruler. A supposed 1" x 2-5/8" label that prints even slightly compressed can produce a barcode that looks fine to the eye but fails warehouse scans.

Step-by-step: Print FNSKU labels from Seller Central

1. Log in to Seller Central and open the SKU or shipment you are preparing.
2. Select the units that need Amazon barcodes.
3. Click Print item labels.
4. Choose the template that matches your actual label stock. Do not guess.
5. Set the number of labels per SKU. Double-check bundle quantities.
6. Download the PDF and open it in a desktop PDF viewer, not just a browser tab.
7. In print settings, choose Actual Size or 100%.
8. Print one test sheet or one test label.
9. Apply a sample and scan it.
10. Run the full batch only after the test passes.

The common UI mistake is selecting a 30-up sheet template but loading a different sheet brand with off-spec spacing. That creates drift by the third or fourth row.

Batch printing tips to avoid misalignment

• Print a test page onto plain paper first, then hold it against the label sheet
• Turn off browser scaling and printer auto-fit features
• Confirm US Letter versus A4 paper settings
• Use the correct driver for Zebra, Rollo, or DYMO units
• Clean thermal printer heads if the barcode edges look fuzzy
• Separate item-label jobs from carton-label jobs so files do not get mixed

In our experience, one failed calibration can waste an entire box of labels. Ten seconds of test printing is cheaper than relabeling 800 units.

Label placement, application, and special cases

General placement rules

The right label size for FBA products only works if the label is placed correctly. Put the barcode on a flat, visible surface. Avoid corners, seams, package folds, curved bottle shoulders, and textured shrink wrap. The scanner needs unobstructed bars and clear space around the code.

Apply the label smoothly. Air bubbles, wrinkles, and lifted corners can block scans. If the package has condensation or dust, wipe it before application.

Covering manufacturer barcodes and multi-pack rules

If the SKU is using FNSKU tracking, the FNSKU should cover any exposed UPC, EAN, or other scannable product code. Partial coverage is risky because a receiving associate may still catch enough of the underlying code for a bad scan. Full coverage is the safer route.

For multi-packs and bundles, label the outer sellable unit, not each internal component unless Amazon’s prep instructions say otherwise. A six-pack shrink bundle should usually show one scannable barcode on the outside of the final retail unit.

Special packaging situations

Apparel is usually labeled on the poly bag rather than directly on the garment package. Small items may need bagging first so the barcode has a flat area. Liquids should use labels that resist smudging and remain attached if the bottle surface gets slightly oily during handling. Tamper-evident prep can also affect where the label sits.

We have seen sellers place barcode stickers over warning text on cosmetics or supplements. That creates compliance issues even when the barcode scans perfectly. Keep required product information visible while still making the barcode easy to read.

Bulk labeling, services, and cost trade-offs

In-house vs pre-printed vs 3PL labeling

There are three main ways to handle labels. First, print in-house. This gives the most control and the lowest direct material cost once volume rises. Second, order pre-printed labels from a print vendor. This works well if SKU counts are stable. Third, use a prep center or 3PL to label inventory before it reaches Amazon.

For a seller shipping 200 units a month, in-house sheet labels may be perfectly fine. For a seller moving 20,000 units across 150 SKUs, a prep center often saves labor, errors, and missed cutoffs. We usually see the break point around the time one staff member starts spending multiple hours per week doing nothing but label prep.

How to estimate labeling costs

Use this formula: (label material + labor + equipment amortization + error cost) / units labeled. Error cost matters more than many sellers expect. One mis-labeled shipment can erase months of savings.

If a prep center quotes $0.11 per unit with strong quality controls, outsourcing may actually save money.

Where to order pre-printed labels and services

Look for commercial print shops that handle barcode work, Amazon prep centers, or 3PLs with FBA-specific labeling experience. Ask about proofing, barcode verification, turnaround time, and whether the provider will rework errors at no charge. A good vendor should understand both product labels and the 4x6 Amazon label workflow for cartons.

Troubleshooting: scanning failures and quality checklist

Common scanning problems and fixes

If labels do not scan, start with four likely causes. First, the print is blurry. Clean the printer or replace low toner. Second, the barcode was resized by scaling. Reprint at 100%. Third, the contrast is weak because gray or color settings were used. Print in solid black. Fourth, the label surface is poor for the package, so edges lift or wrinkle.

Another common issue is using the correct Amazon barcode label size but placing the label over a curved edge. The size is right, the print is right, and the scan still fails because the bars are distorted by the package shape.

Pre-shipment label QA checklist

1. Confirm the correct SKU and barcode path in Seller Central
2. Verify the template matches the physical label stock
3. Measure one sample label to confirm size
4. Scan at least three random units from the batch
5. Check that the FNSKU fully covers any UPC or EAN that should not be exposed
6. Inspect adhesion after 10 to 15 minutes
7. Make sure carton labels are 4" x 6" and visible on the outer box
8. Review shipment quantities before sealing cartons

Print this checklist and keep it at the pack station. Small routines prevent expensive inbound errors.

When Amazon rejects a shipment for labeling errors

Amazon can reject or delay receiving if labels are missing, unreadable, duplicated incorrectly, or placed where scanners cannot read them. If that happens, the fix may involve relabeling remaining inventory, creating a removal order, or paying Amazon to relabel units depending on the status of the shipment and inventory location (Amazon Seller Central, How to prepare and send inventory to Amazon FBA).

Act fast. Review the shipment problem report, compare the affected SKUs against your print files, and isolate whether the issue came from the template, printer, operator, or barcode path setting. In our experience, the fastest recovery comes from identifying the exact failure point rather than reprinting everything blindly.

FAQ — common seller questions about Amazon FBA label sizes

What size are Amazon FBA labels for individual products?

Most individual product labels use a 1" x 2-5/8" FNSKU sticker, which matches Avery 5160-style sheets. This size is common because it fits the barcode and product text clearly while staying small enough for many retail packages.

Can I use Avery 5160 labels for Amazon FBA FNSKUs?

Yes. Avery 5160 is one of the most common choices for FNSKU product labels. Sellers use it because the 1" x 2-5/8" layout is easy to print from Seller Central and works well with laser printers for standard item-label jobs.

What size is an Amazon shipping or box label?

The standard Amazon shipping label size for outer cartons is 4" x 6". Most sellers print these labels on thermal printers because 4x6 roll labels are fast, clean, and less prone to alignment issues than sheet-based shipping labels.

Do FBA labels have to cover the manufacturer barcode (UPC or EAN)?

If the product is using an Amazon FNSKU for tracking, the FNSKU label should cover any scannable manufacturer barcode on the sellable unit. Full coverage helps prevent warehouse associates from scanning the wrong code during receiving.

What printer is best for Amazon FBA labels, thermal or laser?

A laser printer is usually best for low-volume FNSKU sheet labels, while a thermal printer is usually best for 4" x 6" carton and shipping labels. Sellers with higher shipment volume often use both, one for item labels and one for box labels.

What DPI and print settings should I use so the barcode scans?

Use 300 DPI for laser or inkjet whenever possible and 203 to 300 DPI for thermal printers. Print in solid black, set scaling to 100% or Actual Size, and avoid fit-to-page settings because resizing can make the barcode unreadable.

How do I print multiple FNSKU labels per sheet without misalignment?

Choose the exact template that matches your physical label stock, test on plain paper first, and disable printer scaling. Also confirm that the PDF viewer, paper size, and printer driver are all set correctly. Misalignment usually comes from template mismatch or auto-fit settings.

When should I hire a prep center or print labels professionally?

You should consider a prep center when labeling takes several hours per week, error rates start rising, or your team is handling large SKU counts and frequent replenishment cycles. Outsourcing often makes sense once labor and rework cost more than the provider’s per-unit fee.

Are there special label materials I should use for apparel or liquids?

Yes. Apparel usually benefits from labels placed on the outside of a poly bag rather than on delicate retail packaging. Liquids often need labels with stronger adhesive and smudge-resistant surfaces so the barcode stays attached and readable during handling.

What do I do if Amazon rejects my shipment for incorrect labels?

Review the shipment issue details in Seller Central, identify the affected SKUs, and determine whether the problem was caused by wrong size, wrong barcode, poor placement, or print quality. Then rework remaining units, coordinate relabeling if needed, and correct the process before sending the next shipment.
