About SizeMatch
SizeMatch is a free tool that shows how big devices really are by drawing them to scale on the same grid.
What it does
Spec sheets list sizes in millimetres, which are hard to picture. SizeMatch lets you pick two devices, overlay them or place them side by side, and drag them around to see the difference. A life-size mode, calibrated with a bank card, shows the outlines at real-world size on your screen.
Where the sizes come from
Sizes come from manufacturer pages, retailer spec sheets and phone databases. TV and monitor sizes are calculated from the screen diagonal and aspect ratio, and show the screen area only. We list the larger thickness where sources show a range for different colours or materials.
Accuracy and corrections
We check the numbers, but manufacturers update specifications and variants differ by region, so small errors can happen. If you find one, let us know with the model name and a link to the source, and we will correct it.
How the site is funded
SizeMatch is free to use. We may show advertising or add affiliate links in future. If we do, it will be clearly marked, and it will not change the sizes we show.
