The everyday paper size outside North America — prints, certificates and small posters. A4 is a 1:√2 shape, so a typical phone photo (3:4) loses about 6% from the sides. On A4 paper it prints at 93% with a thin white edge, or full size on a borderless printer.
How many pixels is an A4 photo?
Pixels per inch decide how sharp a print looks. Here's what an A4 print needs (portrait; swap the numbers for landscape). Pixels = inches × DPI.
| DPI | Pixels | Megapixels | How it looks |
|---|---|---|---|
| 300 | 2,480 × 3,508 | 8.7 | Sharp, even up close |
| 240 | 1,984 × 2,806 | 5.6 | Good — a little softer up close |
| 150 | 1,240 × 1,754 | 2.2 | Lowest we'd go — fine from across the room |
| 72 | 595 × 842 | 0.5 | Screen only — too low to print |
Will a phone photo fit an A4 frame?
A4 is a 1:√2 shape. Here's roughly how much is trimmed when a photo fills the frame (turned the same way as the frame). Prefer to keep everything? Choose Fit whole photo and add a border instead.
| Your photo | In an A4 frame |
|---|---|
| Phone photo (3:4) | Trims about 6% from the sides |
| Camera photo (2:3) | Trims about 6% from the top and bottom |
| Screenshot or video still (9:16) | Trims about 20% from the top and bottom |
| Square photo (1:1) | Trims about 29% from the sides |
Which frames and mats fit an A4 print?
Fits an A4 frame (21 × 29.7 cm), or an A3 or 30 × 40 cm frame with an A4 mount.
Mat openings are usually about ¼ in (6 mm) smaller than the print on each side, so the edges tuck behind the mat — keep faces and words away from the very edge. The tool shows that strip as a dashed line.

Frequently asked questions about A4 prints
What size should a photo be for an A4 frame?
For a print that's sharp even up close, 2,480 × 3,508 pixels — that's 300 DPI. At 1,984 × 2,806 (240 DPI) it's still a good print, a little softer up close, and 1,240 × 1,754 (150 DPI) is the lowest we'd go — fine from across the room. FrameReady makes the file at the right size for you.
Will my phone photo fit an A4 frame?
Most phone photos are 3:4, so about 6% is trimmed from the sides to fill an A4 frame. Drag the photo to choose what stays, or pick "Fit whole photo" to keep everything and add a border instead.
Can I print A4 at home?
Almost: A4 (21 × 29.7 cm) is about as big as a sheet of paper, and most home printers leave a thin unprinted edge. The print-at-home page can print it on A4 paper full size if your printer has a borderless setting, or at 93% with a thin white edge (fine behind a mat); on Letter paper at 89% with a thin white edge (fine behind a mat). For an exact print without fuss, use a photo shop or online print service.
Is it really free and private?
Yes. Your photo never leaves your device — everything happens in your browser. Nothing is uploaded, there's no sign-up and no watermark.
Is A4 the same as letter size?
Close, but no: A4 is 21 × 29.7 cm (8.3 × 11.7 in), a little narrower and taller than US letter (8.5 × 11 in). Pick the size that matches your frame — FrameReady sizes the file exactly.
What is A4 in centimetres and millimetres?
A4 is 21 × 29.7 cm (210 × 297 mm), or 8.3 × 11.7 in. Frames are sold by exact size, so match the frame's label rather than a near metric equivalent.
