Pixel Dimension

See real sizes for the values in your code

iOS

See the real spacing and sizing of elements on the device you actually ship to. Draw rectangles, circles, and straight lines at exact sizes — px, pt, in, cm, or mm — and import a screenshot to measure against. Built for developers gauging layout values like “move this up 20pt.”

On the device

  • A black canvas with rulers down the left edge and along the bottom, holding a 160pt rectangle, a 621px rounded rectangle, a 196.5pt line, and a circle with a 70pt radius.

    Rulers on both axes, with every shape carrying its own live measurement — mixed units on one canvas.

  • An open menu listing Drawing Color, Add Rectangle, Add Line, Add Circle, Add Text, Add Image, and Show rulers.

    Drop in a rectangle, line, circle, or text — then measure it against whatever is already on screen.

  • Measurement overlays drawn on top of a running app's interface, sizing a card at 160pt by 45pt and a tab bar at 58.3pt tall.

    Measure a real interface in place — here a tab bar comes back at 58.3pt tall, no guessing.
