Photo print sizes: pixels and aspect ratios

Use the size of the image area, not the outside of the frame. Dimensions below are portrait; swap width and height for landscape.

Pixel sizes for photo prints

Print (inches)	Ratio	Pixels at 150 PPI	Pixels at 300 PPI
4 × 6	2:3	600 × 900	1,200 × 1,800
5 × 7	5:7	750 × 1,050	1,500 × 2,100
8 × 10	4:5	1,200 × 1,500	2,400 × 3,000
8 × 12	2:3	1,200 × 1,800	2,400 × 3,600
11 × 14	11:14	1,650 × 2,100	3,300 × 4,200
12 × 18	2:3	1,800 × 2,700	3,600 × 5,400
16 × 20	4:5	2,400 × 3,000	4,800 × 6,000
20 × 30	2:3	3,000 × 4,500	6,000 × 9,000

150 and 300 PPI are calculation examples, not a quality guarantee. Use the print provider's requested density. Focus, cropping and viewing distance still matter.

Match the shape before resizing

A 2400 × 3600 photo fits 4 × 6 or 8 × 12 without changing its ratio. To fill an 8 × 10 print, crop it to 2400 × 3000: 600 pixels are removed from its height. That remaining image gives 300 PPI at 8 × 10 inches.

To keep every edge instead, choose fit with borders. Stretching the photo to the new ratio distorts it.
