Best Angle Finders Reviews & Comparison
Angle finders do just what the name implies: they measure angles and replicate them, which is handy for carpentry, construction, and other building projects. Unlike the handheld protractors familiar to anyone who’s ever taken math and used a protractor, modern angle finders are often digital devices that provide almost instant results and allow the user an incredible range of between 0 and 360 degrees to prevent cutting and measurement errors. As our buying guide to the best angle finders shows, many handy options are available to DIYers and professionals alike.
Coupled with their lightweight and compact design, they are suitable for undertaking a wide range of projects including woodwork and construction. Jobs such as cutting crown molding, laying floorboard or tiles, or cutting a countertop require precision, as pieces must line up perfectly. When re-cuts and re-dos are not options, “eyeballing” where to cut is not enough. The angle finder used hinged arms and a protractor to measure inside and outside corners. Some models even come with embedded magnets that make them indispensable for measuring miter and bevel angles on a wide range of saw benches.
While you have the option of using the familiar, traditional, handheld protractor for measuring angles, you’ll be foregoing the accuracy, ease of use, and speed that comes with using a more modern alternative: angle finders.

Criteria for Choosing the Best Angle Finders
For projects such as woodworking and construction, being off by as little as 1 percent of an angle reading has the potential of throwing your whole project into disarray. In these cases, a super-accurate angle finder is a must-have.
Ideally, an angle finder for commercial use should be accurate to within 0.1-degrees, while one for domestic or DIY projects can be allowed up to +/- 0.3 degrees. Closely related to accuracy is the locking feature. The locking feature enables the user to conveniently lock the arms at an angle of their choice, which preserves the measurement reading for later use.
Broad Measurement Range
A high-end angle finder needs to be versatile, capable of measuring angles within the 0 and 360-degree range. There are some extreme angles that a conventional angle finder will struggle with, while their digital counterpart can measure with utmost ease and impressive speed. The versatility of modern angle finders makes them incredibly easy to use for any project.
For convenience, angle finders should come with a level. The feature saves you the hassle of going to and fro the level and finder with every cut.
A final critical feature is how strong and durable the device is. An angle should withstand the rigorous task of measuring miter and bevel angles in sometimes awkward and hard-to-reach spots. Similarly, it should be able to withstand impact and other environmental conditions like extreme weather conditions.
It should be rust-resistant so it continues providing you with several years of seamless and trouble-free service. Two of the strongest and most durable materials manufacturers tend to use are stainless steel and aluminum.
Ease of Use
In addition to the features mentioned above, the ideal angle finder should be easy to use. Features such as a large, easy-to-read LCD display, a memory feature, and an ergonomic, lightweight, and compact design go a long way. Additionally, an auto shut-off feature, a cut calculator, embedded magnets, and even Bluetooth technology increase functionality.
