Print Image Size Guide (2026)
Print images need 300 DPI. To print at a given inch size, multiply width and height in inches by 300 — a 5 × 7 inch photo needs 1500 × 2100 px.
Print quality is a function of DPI (dots per inch), not screen resolution. A print looks sharp when every inch of paper contains at least 300 pixels of image data. Below 200 DPI, individual pixels start becoming visible; below 150, it's obviously blurry.
The table below shows the pixel dimensions you need for the standard print sizes. Round up rather than down — a slightly oversized source scales down cleanly, but an undersized source can't be recovered.
Pixel dimensions for common print sizes at 300 DPI
| Asset | Dimensions | Ratio | Format | Max size |
|---|---|---|---|---|
| Wallet (2 × 3 in) | 600 × 900 | 2:3 | JPG / TIFF | 3 MB |
| 4 × 6 inch | 1200 × 1800 | 2:3 | JPG / TIFF | 5 MB |
| 5 × 7 inch | 1500 × 2100 | 5:7 | JPG / TIFF | 7 MB |
| 8 × 10 inch | 2400 × 3000 | 4:5 | JPG / TIFF | 10 MB |
| 11 × 14 inch | 3300 × 4200 | 11:14 | TIFF | 15 MB |
| A4 (8.27 × 11.7 in) | 2480 × 3508 | 1:√2 | PDF / TIFF | 15 MB |
| US Letter (8.5 × 11 in) | 2550 × 3300 | 17:22 | PDF / TIFF | 15 MB |
| Business Card (2 × 3.5 in + bleed) | 675 × 1125 | 2:3.5 | 3 MB |
Why DPI matters for print
Screens display at ~72-96 pixels per inch. Print requires ~300. That's a 4x information density difference — a photo that looks crisp on your monitor at 100% zoom will look soft when printed at the same physical size.
The safe rule: for anything you plan to print, capture or download at the highest resolution available. You can always downsize; you can never truly upsize.
How to prepare an image for print
Check the pixel dimensions against the table above for your target print size. If your image is short of the required dimensions, resize to a smaller print instead — never upscale.
Export as JPG at quality 95+ for photos, or as TIFF/PDF for graphics with text. Keep a copy of the master file before any downsize, so future prints at other sizes can start from full resolution.
Frequently asked questions
What resolution do I need for print?
Print uses 300 DPI. To print at a given inch size, multiply the width and height in inches by 300 — a 4 × 6 inch photo needs 1200 × 1800 px.
What is the difference between DPI for print and web?
Screens use 72 DPI; print uses 300 DPI. DPI only matters at print time — on screen, pixel dimensions decide sharpness. A 300 DPI image and a 72 DPI image at the same pixel dimensions look identical on a monitor.
Can I upscale a web image for print?
No. Upscaling a 1080 × 1080 px image to print at 8 × 8 inches results in visible blur and pixelation. Print always requires the source at the target DPI or higher.
What is the best file format for print?
TIFF or PDF for professional printing (they preserve full color depth). PNG is acceptable for graphics with text. JPG works for photos at quality 90+ but loses detail with each save.
What color mode should I use for print?
CMYK for professional press printing, RGB for home inkjet printers. Most print shops convert RGB to CMYK on their end, but designing in CMYK avoids surprise color shifts on brand-critical work.
How do I calculate print size from pixels?
Divide pixel dimensions by 300 to get inches. 3000 px ÷ 300 DPI = 10 inches. To go the other way, multiply your target print inches by 300 to get the minimum pixel dimension.
