Measure distances in a DXF online
Click two points on a drawing to measure the distance between them. Points snap to endpoints, vertices and circle centres, and you get distance, Δx, Δy and the angle — in the drawing's real units.
Free · no sign-up · the file is read in your browser and never uploaded.
Need a quick dimension off a DXF without loading CAD? Open the drawing, click a start point and an end point, and DXFTools reports the straight-line distance plus the horizontal and vertical deltas and the angle in degrees.
Snapping makes it accurate: your clicks lock onto entity endpoints, polyline vertices and circle centres, so you measure between real geometry rather than guessing pixels. Distances are shown in the drawing's units, read from the DXF header.
It runs entirely in your browser — the file is never uploaded — so you can check a dimension on a confidential drawing in seconds, on any device, without an AutoCAD licence.

Frequently asked questions
- Does it snap to the geometry?
- Yes. Clicks snap to entity endpoints, polyline vertices and circle centres, so you measure between real points rather than approximate pixels.
- What does it report?
- The straight-line distance between the two points, the horizontal (Δx) and vertical (Δy) differences, and the angle in degrees — in the drawing's units.
- Do I need AutoCAD or any paid software?
- No. Everything runs in a normal web browser. There is no install, no licence and no account required.
- Do you upload or store my DXF file?
- No. The file is read and processed entirely in your browser using your device's own resources. It is never sent to a server or stored anywhere.
