Hi John thanks for posting. Unfortunately it's not currently possible to display floorplan measurements in inches only. The default units of measurement available are meters or feet. If a default measurement in inches would be helpful for you would you mind adding your thoughts to our Product Feedback section? This goes to our Product team for consideration in future updates.  

I didn't think it was possible but Lucidchart has found a way to make the Imperial System even more useless.

Hi David

I'm sorry to read that you are dissatisfied with our product.

Please feel free to add your feedback to our Product Feedback section too so that we can improve this feature.

Thank you!
