How to use the wallpaper resolution fit guide
Setting a favourite image as a wallpaper and finding it soft, or missing the part you cared about, usually comes down to one of two things: the source has fewer pixels than the screen, or the source and screen ratios differ. Enter the source width and height plus your screen resolution and this page judges both at once.
A wallpaper cannot show gaps, so the math assumes coverage using the larger of the two ratios. A scale of 1 or below means the screen can be filled without enlarging anything; above 1 means the source has to be blown up by that factor. The accompanying 'smallest source' figure is the smallest image at the same ratio that covers the screen with no enlargement.
There is deliberately no list of recommended per-device resolutions here. Manufacturers and operating systems revise those numbers, so a stored table would go stale: read the resolution from your device settings and type it in (checked October 2026). Areas hidden by a clock or widgets, and the extra width some systems use when panning between home screens, differ by platform and are left out of the math.
Frequently asked questions
Having enough pixels does not fix a ratio mismatch: whichever side overflows is trimmed. The two checks are separate, so compare the two ratio rows in the table.
Manufacturers and operating systems revise them, so a written list goes stale quickly. Type in the resolution your device settings report and this page does the math.
It does not. Where and how large those overlays are differs by operating system, so they are left out. Keep an important subject near the middle of the reported coordinates to be safe.
