PrintPixel16×20 Photo Size in Pixels
A 16×20 inch print is a large display frame — the same 4:5 ratio as 8×10, but with more room for detail. Here's how many pixels a sharp 16×20 needs.
16×20 is 406.4 × 508.0 mm (40.6 × 50.8 cm, 16 × 20 in). At 300 PPI that's 4800 × 6000 pixels — roughly 28.8 megapixels.
| Resolution | Pixels |
|---|---|
| 300 PPI | 4800 × 6000 px |
| 240 PPI | 3840 × 4800 px |
| 200 PPI | 3200 × 4000 px |
| 150 PPI | 2400 × 3000 px |
Pixel dimensions are computed from the physical size of 16 × 20 in at each resolution.

| Resolution | Pixels | Physical size |
|---|---|---|
| 300 PPI | 4800 × 6000 px | 40.6 × 50.8 cm |
| 240 PPI | 3840 × 4800 px | 40.6 × 50.8 cm |
| 200 PPI | 3200 × 4000 px | 40.6 × 50.8 cm |
| 150 PPI | 2400 × 3000 px | 40.6 × 50.8 cm |
Pixel counts are computed from the real physical dimensions of 16 × 20 in at each resolution — they are not hard-coded. To get these values for any other print size, use the calculator above.
16×20 at common resolutions
The physical size of 16×20 is fixed — 406 × 508 mm — but the number of pixels needed to fill it depends on the resolution.
| Resolution | Pixels | Megapixels | Practical note |
|---|---|---|---|
| 600 PPI | 9600 × 12000 px | 115.2 MP | Exceeds most camera sensors; useful for heavy cropping or extreme enlargement |
| 300 PPI | 4800 × 6000 px | 28.8 MP | Standard for close-up photo prints |
| 240 PPI | 3840 × 4800 px | 18.4 MP | High-quality prints; sharp at normal viewing distance |
| 200 PPI | 3200 × 4000 px | 12.8 MP | Good quality for wall-mounted prints viewed from arm's length or more |
| 150 PPI | 2400 × 3000 px | 7.2 MP | Acceptable for large prints viewed from a distance |
| 72 PPI | 1152 × 1440 px | 1.7 MP | Screen resolution; not recommended for print |
PPI (pixels per inch) tells you how many pixels fit into one inch of print. 16×20 is exactly 16 inches wide × 20 inches tall. At 300 PPI that's 4800 × 6000 pixels; at 150 PPI it's 2400 × 3000 — half the pixels, covering the same 40.6 × 50.8 cm of paper.
The table above uses the real physical dimensions of 16×20 at each resolution. To get these values for any other print size, use the calculator above.
16×20 uses a 4:5 aspect ratio
16×20 is exactly 4:5 — more square than the 3:2 or 4:3 ratios most cameras produce. That means most photos need cropping to fit without stretching.
A landscape 3:2 photo printed portrait 16×20 loses roughly 47% of its width.
A landscape 4:3 photo printed portrait 16×20 loses roughly 40% of its width.
If your camera shoots 4:5, the photo fits a 16×20 frame with no cropping at all.
If you'd rather not lose part of the image, the practical answer is usually to pick a print size whose ratio matches your photo. TheImage Print Size Calculator checks this for your exact file.
16×20 portrait vs landscape
In portrait orientation, 16×20 is 4800 × 6000 pixels at 300 PPI. Inlandscape it's 6000 × 4800 pixels — the same pixel count, just rotated. 16×20 works well in both orientations: portrait for single-subject displays, landscape for group photos and scenery.
Can my photo be printed at 16×20?
Compare your image's pixel dimensions to the values above. At least 4800 × 6000 pixels are needed to cover 16×20 at 300 PPI. If your image is smaller, the effective PPI drops — the print may still look fine from a normal viewing distance, but will appear softer up close.
The quickest check is tocheck your image with the Image Print Size Calculator. Upload your photo and it shows the exact resolution at 16×20, whether cropping is needed for the 4:5 ratio, and a practical quality verdict. Images are processed entirely in your browser and never uploaded.
Practical details
A 16×20 at 300 PPI needs 4800 × 6000 pixels — roughly 29 MP. Because 16×20 is 4:5, photos shot at 4:3 (many phones) or 3:2 (most DSLRs) will need cropping on the long edges to fit without stretching.
At 240 PPI, 3840 × 4800 pixels is enough for a crisp print at a normal viewing distance. If you plan to display a 16×20 on a wall viewed from a few feet away, 200 PPI (3200 × 4000 pixels) is often entirely acceptable too. At 150 PPI,2400 × 3000 pixels works for large prints viewed from a distance.
16×20 is a popular size for framed portraits, gallery prints and wall displays. Its 4:5 ratio is the most square of the common photo prints, which means cropping is the rule rather than the exception: a 3:2 DSLR photo loses roughly 47% of its width to fit, and a 4:3 phone photo loses about 40%. Compose with that crop in mind, or choose a size that matches your photo's own ratio.
If 16×20 crops too much of your photo, 8×10 photo size in pixels is the same 4:5 ratio at a smaller scale, and 5×7 photo size in pixels offers a less square alternative. For a ratio closer to 3:2, 18×24 photo size in pixels uses 3:4. To preview how your camera's ratio crops on a 16×20 frame, the aspect ratio calculator shows the exact boundaries. To see exactly what a 16×20 would do to your own image, the print quality checker shows the crop and the quality verdict instantly.
