A4 vs 8×10International vs US Standard
They look almost the same size, but A4 is the international standard and 8×10 is the US photo-frame size — and they use different ratios (ISO A vs 4:5), so one file won't fit both.
Quick Answer
What is the difference between A4 and 8×10 print size?
Pixel Dimensions for A4 and 8×10 at 300 DPI
Exact pixel dimensions print shops and home printers need for sharp output. Always export at 300 DPI so the print stays crisp once it is framed.
| Size | Pixels (300 DPI) | Ratio | Area | SnapToSize |
|---|---|---|---|---|
| A4 (portrait) | 2480×3508 px | ISO A (1:√2) | 96.7 sq in | ISO A Pack |
| A4 (landscape) | 3508×2480 px | ISO A (√2:1) | 96.7 sq in | ISO A Pack |
| 8×10 (portrait) | 2400×3000 px | 4:5 | 80 sq in | 4:5 Pack |
| 8×10 (landscape) | 3000×2400 px | 5:4 | 80 sq in | 4:5 Pack |
How Different Are A4 and 8×10, Really?
On size, they are close: A4 covers 96.7 square inches versus 80 for an 8×10, about 21% more area. That small gap is why people assume they are interchangeable. They are not.
The real difference is shape. A4 is taller and a little narrower (8.27×11.69 inches) because it uses the ISO A-series ratio, while 8×10 is the squarer 4:5. Drop an 8×10 design onto an A4 sheet and it leaves uneven margins; force it to fill and it distorts. Same story in reverse. The proportions, not the size, are what make them two separate files.
Why One File Won't Fit Both
A4 and 8×10 come from two different sizing systems, and their aspect ratios reflect that:
The ISO ratio is taller than 4:5, so an 8×10 design placed on A4 floats with extra space top and bottom, and an A4 design squeezed into 8×10 loses height. Keep each at its own ratio. When you specifically need A4 from artwork built at 4:5, a Perfect Fit crop reframes it to the A-series ratio without stretching — you choose what stays in frame.
The clean approach: export 2400×3000 px for 8×10 and 2480×3508 px for A4. SnapToSize generates both from a single upload — no Photoshop, no manual resizing, no guessing which edge to crop. For the full international picture, see ISO vs US print sizes.
One upload becomes both sizes
Drop in your art once. Get A4 and 8×10 back, your whole image kept, each file named and 300 DPI — plus every other Etsy ratio in the same export.
Every standard Etsy ratio — 2:3, 3:4, 4:5, ISO A, plus extras — up to 70 print-ready files from one upload, each ZIP under Etsy's 20 MB limit.
Want one exact ratio instead? Perfect Fit reframes with a focal crop you control — your proportions stay exact, and you decide what stays in frame. See how it works →
Selling to both US and international buyers means an 8×10 and an A4 — two ratios, two exports, and hoping neither came out with odd margins.
Upload once. SnapToSize generates 8×10 and A4 at the correct pixel dimensions and 300 DPI, each ratio handled — guaranteed under 20MB.

Can You Print an 8×10 on A4 Paper?
Yes, but with white borders. A4 is taller and a different shape than 8×10, so an 8×10 design sits inside the sheet with uneven margins — more at the top and bottom than the sides. It prints at full sharpness; it simply does not fill the page, which looks unfinished to a buyer expecting edge-to-edge art.
The clean fix is to give international buyers a true A4 file sized to the sheet, and US buyers an 8×10 for their frames. That way nobody is trimming paper or living with lopsided borders. For the wider set of international sizes, see the A4 print size guide.
A4 or 8×10 — Which Should You Offer on Etsy?
8×10 is essential for US buyers. It is the size that fits the photo frames sold at Target, Walmart, and IKEA in North America, and US shoppers search for it by name. For the US market, 8×10 is non-negotiable.
A4 unlocks everywhere else. The UK, Europe, Australia, and most of Asia frame and print in A-series sizes, not inches. If your listing skips A4, those buyers cannot use your files — and they are a large share of the global market.
Offer both and you serve the whole world from one upload. It is the single easiest way to widen a print listing's reach, with no extra design work.
Frequently Asked Questions
Slightly. A4 measures 210×297mm (8.27×11.69 inches), so it covers about 96.7 square inches versus 80 for an 8×10 — roughly 21% more area. The bigger difference is shape: A4 is noticeably taller and a touch narrower than 8×10, because the two use different aspect ratios.
A4 uses the ISO A-series ratio, 1:√2 (about 0.707) — every A size shares it. 8×10 is a 4:5 ratio (0.800). They are clearly different proportions, which is why a file built for one shows white bars or needs a crop in the other. They are not interchangeable.
At 300 DPI, A4 needs 2480×3508 pixels (portrait) or 3508×2480 (landscape). 8×10 needs 2400×3000 pixels (portrait) or 3000×2400 (landscape). 300 DPI is the standard for sharp prints at these sizes.
Yes, with white borders. An 8×10 design does not fill an A4 sheet — A4 is taller and a different shape — so you get uneven margins, larger at the top and bottom. It prints sharp, it just does not fill the page. For a clean result, provide a true A4 file sized to the sheet.
Not cleanly. 8×10 is 4:5 and A4 is the ISO 1:√2 ratio, so a straight scale leaves white bars and stretching distorts the art. Export each at its own ratio, or use a controlled, distortion-free crop to the A-series ratio when you specifically want A4 from 4:5 artwork.
Offer both. 8×10 is the size US buyers frame; A4 is the standard in the UK, Europe, Australia, and most of Asia, where inch sizes are not sold. Including A4 alongside 8×10 opens your listing to international buyers at zero extra design work. SnapToSize generates 8×10 in the 4:5 pack and A4 in the ISO A pack from one upload.
