About the Screen Size Comparison
A 6.9 inch phone screen and a 6.3 inch one sound close until you see them side by side. This tool draws two displays to real relative scale and computes the true area difference, which is what your hands and eyes actually notice.
How to use it
- 1 Enter the first screen size (and aspect ratio if known).
- 2 Enter the second screen.
- 3 Compare the outlines and the area percentage.
Frequently asked questions
Why does a small diagonal difference feel big?+
Area grows with the square of the diagonal. One extra inch of diagonal can mean 30 percent more screen area.
Do aspect ratios matter?+
A lot. A tall 20:9 screen and a wider 16:9 screen with the same diagonal have different areas and very different grips.
