About PageScale Measure
PageScale Measure lets you calibrate a scale on any webpage and take quick, accurate measurements right on top of plans, maps, product images, or screenshots — no extra software needed. 📐🧭
Why you’ll love it:
a) Calibrate on the fly: Pick two points and enter the real distance to set the scale.
b) Measure anything on-screen: Click two points; get a red line + label instantly.
c) Multiple units: mm, cm, m, in, ft, yd — plus ft+in (e.g., 5′ 7.5″).
d) PNG export: Select an area and export a clean snapshot with your measurements. 🖼️
e)Compact overlay UI: Stays out of the way so you keep maximum screen space.
f) Fast workflow: Undo, clear, show/hide overlay, and more.
HOW IT WORKS (3 steps)
1. Open the page you want to measure → click the extension → Activate on this tab.
2. Click Calibrate → pick two points → enter the known distance.
3. Click Measure, then click two points anywhere on the page to get length + label.
Tip: Change Display units any time (including ft+in) without recalibrating.
EXPORT
Click Export, drag to select the area, and it saves a PNG with the overlay.

Accuracy notes
Always calibrate on the exact zoom level you’ll measure at. If you zoom or change DPI, recalibrate for best accuracy.
Measurements reflect distances on-screen; they’re not a substitute for certified surveying or engineering tools.
