About ScreenStacka

ScreenStacka is a free tool that lets you visually compare TV and screen sizes side by side. Enter any two screen sizes, see them overlaid to scale, and get exact measurements so you know precisely what you're getting before you buy.

Why This Exists

Buying a TV online is weirdly hard. The difference between a 55" and a 65" sounds small — it's just 10 inches, right? But that 10-inch diagonal jump means 39.7% more screen area. You'd never know that from a spec sheet. ScreenStacka shows you the actual difference so you can stop guessing and start deciding.

How It Works

Every calculation on this site uses straightforward geometry. For a 16:9 TV (which is the standard for virtually all modern TVs), the width and height are derived from the diagonal using the Pythagorean theorem. The visual overlay draws both screens to the same scale so the size difference is immediately obvious. No AI-generated nonsense, no sponsored rankings — just math and a picture.

Affiliate Links

ScreenStacka includes links to TVs on Amazon. When you buy through these links, we earn a small commission at no extra cost to you. This is how the site stays free and ad-free. We link to Amazon's highest-rated results for each size — we don't pick favorites or accept paid placements.
