Measure in 3 steps
1
Load a drawing
Drag & drop a PDF or image. Multi-page PDFs are supported.
2
Match the scale
Enter the longest dimension written on the drawing, then click both of its ends to set the scale. The tool also shows how accurate the scale is.
3
Measure length & area
Click to measure length, floor area, and wall area. Overlay furniture rectangles and notes too.
Key features
- Scale calibration — set horizontal and vertical separately, correcting fax/scan distortion. The tool shows an estimated accuracy (high / medium / low) and suggests a longer dimension when it is low.
- Metric & imperial units — mm, cm, m, ft, or in. Type feet-inches such as 12'-6" straight from the drawing.
- Length measurement — measure distance with a polyline. Shift snaps to 15°; double-click to finish.
- Zoom — zoom the drawing with the mouse wheel or a two-finger pinch on a trackpad, phone, or tablet.
- Page rotation — turn a sideways page 90° left or right, page by page; the PDF export keeps the rotation.
- Floor area — draw a polygon and read the area in m² or ft². Register multiple areas.
- Wall area — length × height, with a per-length height you can set individually.
- Furniture layout (rectangles) — enter width and depth to place, move, and rotate scaled rectangles.
- Annotations (notes) — add and move notes at any point on the drawing.
- Auto-save & export — work is auto-saved on your device. Export to PDF or save/restore a project file (.data).
Great for
Planning DIY and renovation layouts, pulling dimensions off a PDF drawing, estimating floor and wall areas of a room, and testing furniture layouts. Because images never leave your device, it is safe for company drawings and private floor plans alike.
