Why Resize an Image in Inches?
US print sizes — Letter (8.5×11 in), 4×6 photo, 5×7, 8×10 — are measured in inches. A printer, photo lab, or publisher will ask for images at a specific inch size and DPI. Entering dimensions in inches lets you target those sizes directly and see the resulting pixel count before you resize.
The formula is simple: pixels = inches × DPI. A 4×6 inch photo at 300 DPI produces a 1200×1800px image. At 150 DPI it produces 600×900px — half the resolution, one quarter the file size. Choose the DPI that matches your print destination.
Common US Print Sizes and Their Pixel Equivalents
| Print size | Inches | At 150 DPI (px) | At 300 DPI (px) |
|---|---|---|---|
| Wallet | 2.5 × 3.5 in | 375 × 525 | 750 × 1050 |
| 4×6 photo | 4 × 6 in | 600 × 900 | 1200 × 1800 |
| 5×7 photo | 5 × 7 in | 750 × 1050 | 1500 × 2100 |
| 8×10 photo | 8 × 10 in | 1200 × 1500 | 2400 × 3000 |
| US Letter | 8.5 × 11 in | 1275 × 1650 | 2550 × 3300 |
| US Legal | 8.5 × 14 in | 1275 × 2100 | 2550 × 4200 |
| Tabloid / Ledger | 11 × 17 in | 1650 × 2550 | 3300 × 5100 |
When to Use Each DPI
72 DPI — web and screen
Standard screen resolution. Use for images that will only be viewed on a monitor — website photos, email images, and social media. Printing at 72 DPI produces blurry output.
96 DPI — Windows default
Windows default screen DPI. Images at 96 DPI look correct at 100% zoom on most Windows monitors. Not suitable for printing — use 150 or 300 DPI for physical output.
150 DPI — home and office print
Good for documents, reports, and presentations printed on a home inkjet or office laser printer. Half the file size of 300 DPI with acceptable quality at normal reading distance.
300 DPI — photo labs and professional print
Required by photo labs (Walgreens, CVS, Shutterfly) and professional printers. At 300 DPI, prints look sharp with no visible pixels. Always use 300 DPI for photo prints.

Is inch the same as inch in printing?▼
Yes — 1 inch = 2.54 cm exactly. If your design is specified in centimeters, use the Resize Image to CM tool instead. Use this tool when dimensions are specified in inches.
Does resizing to inches change the image format?▼
No. JPG input produces JPG output. PNG input produces PNG output. The format is preserved. Only the pixel dimensions change.
Is my image uploaded to a server?▼
No. All resizing happens entirely in your browser using the Canvas API. Your image file never leaves your device.
