Scale a floorplan in under 2 minutes
A fast, repeatable workflow for turning any plan into a 1:50 or 1:100 submission-ready file with a clear scale bar.
A scaled floor plan is a measurable drawing, not a visual sketch. When a reviewer can verify dimensions quickly, your submission moves faster. This workflow helps you take an existing plan and export a compliant PDF at a consistent scale, with a visible scale bar.
Start with a clean upload
Use the most recent plan export you have. A clean, high-resolution image gives the point selector the best chance of staying accurate once the plan is scaled.
- Use the highest resolution export available.
- Crop out borders or title blocks that do not need scaling.
- Keep annotations visible so the scale bar matches the review copy.
- Make sure at least one reliable real-world distance is visible on the plan.
Choose reliable reference points
Pick points that reflect a trustworthy, real-world measurement. Longer spans reduce error and produce a more accurate scale.
- Use structural points like wall corners or grid lines.
- Prefer longer distances over short interior details.
- Avoid curved or angled segments unless you can measure them precisely.
Calibrate with two points
Enter the real distance in meters and let the calculator lock in the ratio. Double-check the units before exporting so you do not scale a plan by the wrong factor.
Check the ratio before export
Most UK submissions expect 1:50 or 1:100 for internal layouts. If your application specifies a ratio, match it exactly to avoid validation questions.
Export with a scale bar
The final PDF includes a clear scale bar so reviewers can verify the ratio without guesswork. This avoids rework and keeps approvals moving.
Common mistakes to avoid
- Using a marketing floor plan marked as not to scale without recalibration.
- Selecting two points that are too close together.
- Forgetting to include a scale bar or stated ratio on the export.
- Mixing feet and meters when entering the real distance.
