What’s New?

 

Scale Converter

This tool helps you quickly translate between real-world dimensions and scaled drawing sizes (and vice versa). Simply choose your scale—whether it’s 1:50, 1:100, or another ratio—select your preferred units, and get instant results. It’s particularly handy when you’re working on models, technical drawings, or preparing presentations.

 

Reverse Scale Finder

Got a drawing but not sure what scale it’s in? We’ve all been there. With this tool, you can measure one dimension you recognize and get an estimate of the original scale. It’s especially useful when working with printed plans or scanned drawings where the scale might not be immediately clear.

 

Paper Size & Drawing Layout Helper

Not sure what scale to use to fit your design on an A3 or A1 sheet? This tool takes your real-world drawing dimensions and suggests appropriate scales that will work with your chosen paper size, accounting for margins and orientation options.

We’ve also put together a PDF guide that covers the essentials you might find useful to have on hand:

  • What scale is and why we use it
  • How to convert measurements
  • Choosing the right scale for different drawing types
  • Paper size reference table
  • A quick scale conversion chart

Feel free to download it, print it out, and keep it in your studio space or wherever you do your work—sometimes having a physical reference nearby can be really helpful.

Why We Built These

We remember how overwhelming scale concepts can feel when you’re starting your architectural education. Even as you progress, there are moments when a quick reference or calculation tool can save time and reduce uncertainty. These resources came from wanting to remove some of that guesswork and help streamline your drawing process.

We hope these tools prove useful as you continue developing your architectural skills. Happy drawing!
