What is the dp to px formula?

px = dp × (screen dpi ÷ 160). mdpi at 160dpi is the baseline where 1dp equals 1px.

When should I use sp instead of dp?

Use sp for any text size so it respects the user's accessibility font scale, and dp for everything else — padding, margins, icon and view sizes.

Which buckets do I still need assets for?

In practice xhdpi, xxhdpi and xxxhdpi cover almost all shipping devices; vector drawables remove the need for buckets entirely.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.

sp behaves like dp but is multiplied by the user's font scale setting, so always size text in sp.
