Print Scale & DPI
Printed size, fit and resolution for plotting drawings
Drawing & output
Printed size = real size ÷ scale. Print at 100% (no "fit to page") to keep the scale true.

About Print Scale & DPI
The print scale and DPI calculator tells you how big a drawing prints at a given scale and whether it fits your sheet. Enter the real-world width and height of what you are drawing, the drawing scale as 1:N, and a target sheet — the tool returns the printed size in millimeters and a clear fit verdict.
The core relationship is simple: printed size equals real size divided by the scale. A 20 m building at 1:100 prints 200 mm wide, comfortably on A3 in landscape but tight on A4. The fit verdict distinguishes fitting with margin to spare, fitting with little margin, and being too large for the chosen sheet.
A DPI setting adds the raster dimension: the tool converts the printed size into pixels at your chosen print resolution, which is what you need when exporting a plan as an image. For crisp line work, export at 300 DPI or higher. It runs free in your browser — and remember to print at 100%, never “fit to page,” to keep the scale true.
How to use Print Scale & DPI
- Enter the real-world width and height of the drawing content, in meters.
- Set the drawing scale as 1:N — for example 100 for a 1:100 plan.
- Choose the target sheet and the print resolution in DPI.
- Read the printed size, the fit verdict, and the raster size in pixels at that DPI.
