3:4 Print Sizes in Pixels
3:4 sits between the tall 2:3 and the squarer 4:5. Its sizes run from 6×8 to 18×24 inches, and the 18×24 master at 300 DPI is 5,400 × 7,200 pixels.
| Print size | cm | Pixels at 300 DPI | 200 DPI | 150 DPI |
|---|---|---|---|---|
| 6 × 8 in | 15.2 × 20.3 | 1,800 × 2,400 | 1,200 × 1,600 | 900 × 1,200 |
| 9 × 12 in | 22.9 × 30.5 | 2,700 × 3,600 | 1,800 × 2,400 | 1,350 × 1,800 |
| 12 × 16 in | 30.5 × 40.6 | 3,600 × 4,800 | 2,400 × 3,200 | 1,800 × 2,400 |
| 18 × 24 in | 45.7 × 61 | 5,400 × 7,200 | 3,600 × 4,800 | 2,700 × 3,600 |
Pixels = inches × DPI, rounded to the nearest whole pixel. 300 DPI is the print-shop standard for prints seen up close; 200 is fine on a wall; 150 is the floor. Etsy itself sets no DPI rule.
What sellers use this ratio for
- Wall art sets sold in 12×16 and 18×24, two of the most common frame sizes outside the 2:3 family.
- Portrait-style prints where 2:3 feels too narrow and 4:5 too square.
- Bundles that include 3:4 alongside 2:3 and 4:5 so buyers can choose any frame they already own.

Print Size & DPI CalculatorFrequently asked questions
How many pixels is an 18×24 print at 300 DPI?
5,400 × 7,200 pixels. At 200 DPI it is 3,600 × 4,800, and 150 DPI needs 2,700 × 3,600. The table lists every 3:4 size the same way.
Can I print a 2:3 file at 12×16?
Only with a crop: 12×16 is 3:4, so a 2:3 file loses about 11% of its height to fill the paper. The calculator shows the crop share for any file you enter.
Which is more common on Etsy, 3:4 or 4:5?
Both appear in many multi-ratio bundles. 4:5 is tied to the very common 8×10 and 16×20 frames; 3:4 is tied to 12×16 and 18×24. Offering both avoids sending a buyer to a crop.
Need 300 DPI files for every ratio?
