How to Measure PDF Drawings
The scale is usually printed in the title block.

Choose your drawing
Click Choose PDF file or drop the plan on the tool above.

Set the scale
Choose the Drawing scale, such as 1:100, and the Units. Pick Distance or Area.

Click a page and drag
Drag across a wall or a room. Each size is listed; click Save measurements to keep them on the drawing.
How Scale Measuring Works
A drawing at 1:100 shows a 5 metre wall as 5 centimetres on the page. Measuring with a ruler on a print works, but only if it printed at exactly the right size, and you still have to do the sums.
When you measure PDF pages here, the distance is worked out from the page itself, so printing and zoom do not matter. The scale turns it into real-world size: metres for buildings, millimetres for parts, feet and inches if you prefer.
Areas are width times length of the box you drag, shown in square units.
Distance
Drag from point to point.
Area
Drag a box over a room.
Saved on the plan
Red lines and labels.

Which Scale for Which Drawing?
Use the one printed on your drawing.
| Typical scale | 1 cm on the page is | |
|---|---|---|
| Floor plans | 1:50 or 1:100 | 0.5 m or 1 m |
| Site plans | 1:200 or 1:500 | 2 m or 5 m |
| Details and parts | 1:1 to 1:20 | 1 cm to 20 cm |
