How many pixels for my packaging insert or thank-you card?

Conclusion: At 300 DPI, multiply each side in inches by 300. A common 4×6 in insert is 1,200 × 1,800 px. Add ~0.125 in bleed if color goes to the edge, keep type inside a ⅜ in safe margin, and make QR codes at least 1 in square. Use the calculator, then download a blank PNG template.

Formula: pixels = inches × DPI. Landscape swaps width and height. Bleed expands the full canvas beyond trim.

Seller checklist

How it works

Pixels = inches × DPI

Print shops and Canva/Photoshop artboards for physical cards are sized in pixels at a target DPI. For a sharp insert, use 300 DPI so a 4 inch edge becomes 1,200 pixels. This page applies that formula to seller-friendly presets, optional bleed, a ⅜ inch safe margin, and a 1 inch QR guide — then can export a blank PNG with those guides drawn in.

Amazon FBA sellers typically place thank-you, care, or storefront cards inside the sealed retail unit before inbound. The card must not change outer dimensions or create pressure on the product. Policy wording for reviews is separate from file size — keep requests for feedback honest and unincentivized.

Questions

FAQ

How many pixels is a 4×6 Amazon packaging insert at 300 DPI?

1,200 × 1,800 pixels in portrait (or 1,800 × 1,200 landscape). Multiply each side in inches by 300.

What size should an Amazon FBA thank-you card be?

Business card 3.5×2, compact 3×5, and postcard 4×6 are the usual starting points. Choose whatever fits inside the sealed package without bulging.

What DPI should I export?

300 DPI for most print shops. 150 DPI is a draft compromise. 72 DPI is screen-only and will look soft on paper.

Do I need bleed?

Yes if color or photos go to the cut edge — about 0.125 in per side is common. Keep text and QR codes inside the safe margin.

How big should the QR code be?

At least 1 inch square at print size (300×300 px at 300 DPI), with a quiet zone. Test-scan a printed proof before a bulk order.

Are packaging inserts allowed on Amazon?

Usually yes when they sit inside the sealed unit and do not change dimensions. Review asks must be for honest feedback only — check current Seller Central rules before printing thousands of cards.
