PDF Drawing Measure runs in the browser without creating an account. Enter relevant values or select a file, then generate and download a result. File processing stays on the device. Render page 1 of a PDF and click vertices to measure distance or polygon area at a chosen scale. Use a known length to calibrate; measurements are approximate, not CAD-certified.
Choose a task. Inputs stay in this page only.
Use Simple / draw for rectangles, circles and base-height triangles. Choose a shape tab above for other dimensions. Each shape keeps its own measurements.

Enter width A=10 and height B=8 in metres, then subtract a 2×2 m section.
Choose mm, select Circle and enter diameter A=2000. The radius is 1 m, so the area is π×1².
New points and dragged vertices align to the nearest grid position. Changing the spacing does not resize completed shapes.
The field expects the diameter. Double a known radius first: a 1 m radius means a 2 m diameter.
No. The spacing affects new points and future vertex movement. Turn snapping off to enter arbitrary precise coordinates.
Calculate triangle area and perimeter from the lengths of all three sides. All side lengths must form a nondegenerate triangle and share the same unit.
Calculate trapezoid area using its two parallel bases and perpendicular height. The height is the perpendicular gap between the parallel bases, not a sloping side.
Using these sample input values gives the first labelled output above. Requires six equal sides and six equal internal angles.
No. Replace the examples with your real values. Requires six equal sides and six equal internal angles.
Find ellipse area and a Ramanujan approximation for its circumference. Ellipse perimeter is an approximation; semi-axes are half-dimensions, not full widths.
