Troubleshoot aspect ratio fit calculator

Check these settings if the published page behaves differently from the editor.

Why do the sizes not add up to the box exactly?

Sizes are rounded to the set decimal places; the space or crop per side gets one more place, so 267 px is 133.5 px a side.

Why does it say about 16:9?

Sizes such as 1366 × 768 simplify to 683:384, within 1.5% of 16:9, so the nearest common ratio is shown too.

Why is one box field missing?

In set-the-width or set-the-height mode only that side matters, so the other is hidden.

It asks for a width and height above 0.

Every size needs a positive number; empty or zero fields pause the result.
