MEASURE BEFORE YOU UPGRADE

A clearer picture.
Down to the
numbers.

Screen sizes can be misleading.
Compare the dimensions, understand the pixels,
and make room for what comes next.

Enter your numbers to make a measurement.

Flat active-picture geometry. Outer housings, curvature, stands and software scaling are not modeled.

TRANSPARENT BY DESIGN

The shape. The math.
The parts we can’t predict.

We show the formulas, keep the assumptions visible, and separate screen geometry from product claims. No invented ratings. Just useful measurements.
