The short answer
- 4×6 in102×152 mm — aspect ratio 3:2
- 5×7 in127×178 mm — aspect ratio 7:5
- 8×10 in203×254 mm — aspect ratio 5:4
- 11×14 in279×356 mm — aspect ratio 14:11
- 16×20 in406×508 mm — aspect ratio 5:4, exactly twice 8×10 on each side
- CroppingFour different shapes among the five sizes, so moving a photo between them means cropping one pair of edges or leaving white borders — except 8×10 to 16×20, which share a shape

| Size | Inches | Millimeters | Aspect ratio | Area | Area vs 4×6 |
|---|---|---|---|---|---|
| 4×6 | 4×6 in | 102×152 mm | 3:2 | 24 in² (154.8 cm²) | 100% |

Millimeters converted at 1 in = 25.4 mm exactly and rounded to the nearest mm. The sizes themselves are defined in inches. Aspect ratios are written long side first. Area in cm² uses 1 in² = 6.4516 cm²; the percentage is the area divided by the area of a 4×6 (24 in²), rounded to whole percent.

Pixel counts are the inch dimensions multiplied by the dots per inch. They say how many pixels fill the print at that density, not what any lab requires; check the lab's own guidance for the density it prints at.
What the numbers mean
The five sizes have four different aspect ratios: 3:2 (4×6), 7:5 (5×7), 5:4 (8×10 and 16×20) and 14:11 (11×14). A photo that fills one shape does not fill a different shape at the same proportions. When the lab fills the larger frame, it crops the edges that would otherwise fall outside.
Going from 4×6 (3:2) to 5×7 (7:5): scale the 4×6 to 5 inches wide and the height reaches 7.5 in — 0.5 in too tall for the 5×7 frame. The lab crops 0.25 in (6.35 mm) from the top and bottom, or you accept white borders on the left and right.
Going from 4×6 (3:2) to 8×10 (5:4): scale the 4×6 to 8 inches wide and the height reaches 12 in — 2 in too tall. The lab crops 1 in (25.4 mm) from the top and bottom, or you accept white borders on the sides. From 4×6 to 11×14 (14:11) the same happens at a larger scale: 11 inches wide gives 16.5 in of height, 2.5 in too tall, so 1.25 in (31.75 mm) goes from the top and bottom.
Going from 5×7 (7:5) to 8×10 (5:4): scale the 5×7 to 8 inches wide and the height reaches 11.2 in — 1.2 in too tall. The lab crops 0.6 in (15.2 mm) from the top and bottom, or you accept white borders on the sides.
8×10 to 16×20 is the one enlargement on this page with no cropping: both are 5:4, and 16×20 is exactly twice 8×10 on each side, four times the area. 8×10 and 11×14 are close but not the same shape (1.25 vs 1.27): scaled to 11 in wide, an 8×10 is 13.75 in tall, 0.25 in short of the 14 in frame, so either 0.125 in (3.2 mm) of white shows at the top and bottom, or scaling to the full 14 in height crops 0.1 in (2.5 mm) from each side. 11×14 to 16×20 runs the other way: at 16 in wide the height is 20.36 in, so 0.18 in (4.6 mm) is cropped from the top and bottom.

FAQ
Can I print a 4×6 photo as 8×10 without cropping?
No. A 4×6 photo has a 3:2 aspect ratio; an 8×10 print has a 5:4 ratio. Scale the 4×6 to 8 inches wide and the height reaches 12 in — 2 in taller than the 8×10 frame. The lab crops 1 in (25.4 mm) from the top and bottom, or you accept white borders on the sides.
Can I enlarge an 8×10 to 16×20 without cropping?
Yes. Both are 5:4 — 8:10 and 16:20 reduce to the same ratio — so a 16×20 is exactly twice the width and twice the height of an 8×10, four times the area, and nothing is cropped.
What is a 4×6 print in millimeters?
4×6 in converts to 101.6×152.4 mm at 1 in = 25.4 mm exactly, usually written as 102×152 mm. Kodak's printer documentation lists the same paper as 101×152 mm.
Which print size matches a 3:2 photo?
4×6 in. Its long side is 1.5 times its short side, the same as a 3:2 photo, so nothing is cropped. A 5×7 print is 7:5 (1.4), an 11×14 is 14:11 (about 1.27), and 8×10 and 16×20 are 5:4 (1.25), so a 3:2 photo loses part of its long side on all of them, or gets white borders.
Is wallet size a standard print size?
No single size. Shutterfly lists wallet prints as 2.5×3.5 in; Walgreens sells 2×3 in wallet prints. Because the two shapes differ (7:5 versus 3:2), check the lab's own size list before ordering.
