Top 10 Digital Protractors

This wiki has been updated 27 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 accurately without as much effort. This makes life easier for woodworkers and other contractors who rely on precise 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.

Editor's Notes

June 04, 2020:

Downgraded the General Tools 822 since the arm locking mechanism tends to move the blade, which can be very frustrating since you have to hold the blades in place while you tighten.

Downgraded the iGaging Digital because of reports that the blades may arrive slightly warped. They can still be used effectively as is but it does limit their use as a straightedge.

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.
