About pixels ↔ dp

Android measures screens in density-independent pixels (dp) so the same layout looks about the same size on phones with different pixel densities.

Formula

px = dp × dpi ÷ 160. At xhdpi (320 dpi) 16 dp is 32 px; at xxhdpi (480 dpi) it is 48 px. To go the other way, dp = px × 160 ÷ dpi.

Density buckets

ldpi 120, mdpi 160 (the baseline), hdpi 240, xhdpi 320.
xxhdpi 480 and xxxhdpi 640 for high-resolution screens.

Use dp for sizes, sp for text

Use dp for layout dimensions and sp for text so fonts respect the user's font size setting.

A worked example

A phone with a 1080 × 2400 pixel screen and a density of 420 dpi has a width of 1080 × 160 ÷ 420 ≈ 411 dp. A button designed as 48 dp tall is 48 × 420 ÷ 160 = 126 px on that phone, but 144 px on a 480 dpi (xxhdpi) one.

Tips

Design in dp and let Android convert it, rather than hard-coding pixels.
Supply image assets for several densities, or use vector drawables so one file fits all.
Keep touch targets at least 48 dp so they are easy to tap.

Questions people ask

px = dp × dpi ÷ 160. This tool converts your value to dp first, then applies that formula for every density bucket.

xxhdpi (480 dpi) is the most common baseline for exporting Android assets today, but check your project's target density.

A pixel value only means one dp value once you know which screen density it was measured on, since dp is density-independent.
