This wiki has been updated 11 times since it was first published in March of 2017. Whereas an old-school protractor requires lots of manual work to line up your angles, a digital model can measure more precisely without as much effort. This makes life easier for woodworkers and other tradesmen who rely on accurate measurements daily. Plus, many of today's options can save data straight to your phone or computer, which means less time spent scribbling on your notepad. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki. Skip to the best digital protractor on Amazon.

Editor's Notes

March 28, 2019:

The Bosch 220 MF is a multipurpose tool from a trusted brand, making it a quality addition to the list. Professional contractors have enjoyed exceptional results using it for cutting roofs, installing crown, and creating wood products, among other applications. We removed the Calculated AccuMaster due to a lack of availability.

Dropped the iGaging Bladed several slots for a few reasons: some users have experienced issues with the battery cover not shutting flush with the tool, which can be irritating. People have also noted a tendency for the protractor to reset itself at zero on its own sometimes. On the other hand, we opted for a modest increase to the ranking of the General Tools 822 due to consistent reports of durability, accuracy, a quality locking mechanism, and a helpful auto-shutoff function — all at an affordable price.
