Print Size Pixel Chart
Find the pixel dimensions needed for common photo and paper sizes at 150, 200, 240, and 300 PPI.
Reviewed October 8, 2026
Choose a print size, then use the column that matches your quality target. The dimensions work in portrait or landscape orientation: swap width and height when you rotate the print.
Not sure how many pixels your file contains? Use the image DPI checker to read its dimensions and available resolution metadata without uploading it, then compare the result with this chart.
Pixels needed for common print sizes
| Print size | 150 PPI | 200 PPI | 240 PPI | 300 PPI | Ratio |
|---|---|---|---|---|---|
| 4 x 6 in | 600 × 900 | 800 × 1,200 | 960 × 1,440 | 1,200 × 1,800 | 2:3 |
| 5 x 7 in | 750 × 1,050 | 1,000 × 1,400 | 1,200 × 1,680 | 1,500 × 2,100 | 5:7 |

| 8.5 x 11 in | 1,275 × 1,650 | 1,700 × 2,200 | 2,040 × 2,640 | 2,550 × 3,300 | 17:22 |
| 10 x 15 cm | 591 × 886 | 787 × 1,181 | 945 × 1,417 | 1,181 × 1,772 | 2:3 |
| 11 x 14 in | 1,650 × 2,100 | 2,200 × 2,800 | 2,640 × 3,360 | 3,300 × 4,200 | 11:14 |
| 11 x 17 in | 1,650 × 2,550 | 2,200 × 3,400 | 2,640 × 4,080 | 3,300 × 5,100 | 11:17 |
| 16 x 20 in | 2,400 × 3,000 | 3,200 × 4,000 | 3,840 × 4,800 | 4,800 × 6,000 | 4:5 |
| 18 x 24 in | 2,700 × 3,600 | 3,600 × 4,800 | 4,320 × 5,760 | 5,400 × 7,200 | 3:4 |
| 24 x 36 in | 3,600 × 5,400 | 4,800 × 7,200 | 5,760 × 8,640 | 7,200 × 10,800 | 2:3 |
For close-viewed photo prints, 300 PPI is the usual high-quality target. A 240 PPI file is often sufficient for framed photos, 200 PPI works for many general prints, and 150 PPI is more suitable for large prints viewed from farther away. See the printing PPI guide before choosing a lower target.
How to calculate pixels for a print
Multiply each edge in inches by the target PPI. An 8 × 10 inch print at 300 PPI needs 2,400 × 3,000 pixels. For centimeters, divide each edge by 2.54 first, then multiply by PPI. A 10 × 15 cm photo at 300 PPI is approximately 1,181 × 1,772 pixels.
PPI describes the image pixels placed in each printed inch. Printer DPI describes how a printer lays down ink or toner. Labs often use “DPI” when requesting image resolution, but the pixel calculations in this chart are technically PPI.
Orientation, crop, and bleed
Rotating a print does not change the number of pixels required. A landscape 3,000 × 2,400 image and a portrait 2,400 × 3,000 image both fit an 8 × 10 inch print at 300 PPI.
Cropping is different. Most cameras use a 3:2 or 4:3 aspect ratio, while an 8 × 10 print uses 4:5 and US Letter uses 17:22. If the ratios do not match, crop the image or add borders. Commercial layouts may also require bleed beyond the finished dimensions, so follow the printer's template and keep important details away from trim edges.
Check the print sizes your image supports
The photo print size calculator compares one image with common print sizes and reports its effective PPI. Use the image DPI checker when you also need embedded resolution metadata, pixel dimensions, and file details.
Frequently asked questions
How many pixels are needed for a 4 × 6 photo?
Use 1,200 × 1,800 pixels at 300 PPI, 960 × 1,440 at 240 PPI, 800 × 1,200 at 200 PPI, or 600 × 900 at 150 PPI.
How many pixels are needed for 8.5 × 11 inches?
US Letter requires 2,550 × 3,300 pixels at 300 PPI or 2,040 × 2,640 pixels at 240 PPI. Its 17:22 ratio differs from common camera ratios, so photos may need cropping or borders.
What size is 3,000 × 2,400 pixels?
It is 10 × 8 inches at 300 PPI, 12.5 × 10 inches at 240 PPI, 15 × 12 inches at 200 PPI, or 20 × 16 inches at 150 PPI.
Why does an 8 × 10 print crop my camera photo?
Most cameras capture 3:2 or 4:3, while 8 × 10 is 4:5. Those proportions do not match, so a full-bleed print requires cropping.
