You can download and print your floor plans in different formats and scales, such as 1:50, 1:100, ½"=1´-0", etc. Please find all details on how to do it in this article: 

Save and Print Your Floor Plans

If you print to scale, for example, 1:50, please make sure you have the correct printer settings to get your printed floor plan in the correct scale:

• Do not open and print from a browser.
• Instead, open and print your floor plan in Adobe Acrobat Reader to make sure that your printer settings are correct.

How to print with the correct settings:

1. Open Adobe Acrobat Reader.
2. Choose Actual Size (and not reduce over-sized pages).
3. Click Properties and check that you have the correct paper size for your floor plan.
4. Then print your floor plan to scale.
