5:4 aspect ratio (1.25:1): resolutions and sizes

5:4 means 5 units wide for every 4 tall, so width ÷ height = 1.25 and the height is 80% of the width. Exact 5:4 sizes are whole multiples of 5 × 4, such as 1280 × 1024 (256 × 5 by 256 × 4).

Your numbers, worked

gcd(1280, 1024) = 256

1280 ÷ 256 = 5

1024 ÷ 256 = 4

1280 ÷ 1024 = 1.25

Show how the gcd was found
  1. 1280 = 1 × 1024 + 256
  2. 1024 = 4 × 256 + 0

Divide the larger side by the smaller, then divide the last divisor by the remainder until the remainder is 0. The last divisor is the gcd.

Whole number, so no rounding is needed.

Pixel-exact: a 5:4 size needs the width to be a multiple of 5, and 1280 is 256 × 5.

Questions

What resolutions are 5:4?

900 × 720, 1280 × 1024, 1350 × 1080, 1800 × 1440 and 2700 × 2160 are exactly 5:4. Any size whose width is a multiple of 5 and whose height is the same multiple of 4 is exact.

How do I work out a 5:4 height from a width?

Multiply the width by 4 and divide by 5: 1280 × 4 ÷ 5 = 1024. The other way, width = height × 5 ÷ 4.

How much of a 5:4 image does a 9:16 crop keep?

45%. The share kept is the smaller decimal divided by the larger: 0.563 ÷ 1.25. Padding a 5:4 image to 9:16 instead fills the same share of the canvas.
