Why is 100% scale different from export scale in Figma?

Question

Layout

Making PixelPerfect from Figma layout. I noticed that inside Figma, if you make a 100% scale, this is one size, and if you export to png, then the picture is a quarter smaller, why? And if you copy the built-in sizes with Figma, then nothing converges at all, neither rounding, nor sizes.

What scale to believe to be PixelPerfect?

Answer 1

You may have entered incorrect data for export. Figma is able to scale images
Also there is an option that you export a FRAME which has empty spaces around the image

Answer 2

Also, check in the prototype settings what screen size is set. If the design tab has one screen size, and the prototype tab has a different one, then there are also distortions
