What you get

Know the exact sizes, spacing, and alignment of elements on your screen.

With PixelSnap, you can replace visual estimates with pixel measurements while reviewing a layout on your Mac. Click and drag around an element to see its dimensions or the distance to nearby objects. You can measure several objects on the same screen, making it easier to compare sizes and spot inconsistent spacing.

You can also check whether elements line up horizontally or vertically using guides that snap into place and stay on screen. When small details are hard to isolate, adjusting detection tolerance helps you include subtle edges such as shadows and gradients.

When you need to show someone what you measured, you can capture the measurements in a screenshot. Through the CleanShot integration, you can edit and save that capture, giving you a visual reference to share when discussing layout changes.

  • Replace spacing guesses

    You get pixel distances between elements so you can identify uneven gaps in a layout.

  • Compare several objects

    You can measure multiple elements on one screen to check whether their dimensions match.

  • Spot alignment problems

    You can hold snapping guides on screen to check horizontal and vertical alignment.

  • Share measured references

    You can capture your measurements in screenshots, then edit and save them through CleanShot.

Best for

  • You design interfaces and need to check spacing and dimensions.
  • You develop websites and review layout consistency.
  • You need to share precise visual references for design changes.

Skip it if

You probably don't need it if rough visual checks are enough and you rarely need exact on-screen measurements.
