360 Protractor: Full-Circle Angles Made Easy to Read

What a 360 protractor does that a 180 one cannot

A standard half-circle protractor only reads to 180 degrees, so for a wide, obtuse or reflex angle you end up turning the tool over and subtracting in your head. A full-circle 360 protractor reads any angle in one placement, which removes a common source of mistakes when you are measuring odd corners around the home or workshop.

Easy to read: why a large digital display helps

The fine engraved graduations on a printed protractor are hard on tired eyes, and in ordinary light a one-degree misread is easy — and that single degree is enough to spoil a cut and waste a board. A digital angle finder shows the angle as large, high-contrast figures, so you simply open it to the angle and read the number. There is nothing to line up against a tiny tick mark.

Simple to use, not fiddly

You do not need to be a gadget person. There are two actions: open the arms until they sit flat against the angle, and press hold to keep the reading while you move to the saw. No menus, no calculations. It is the kind of upgrade a son or grandson tends to recommend precisely because it is simpler than the old brass-and-boxwood way.

Specs that matter for readability and durability

• Full 0–360° range on a clear LCD
• Hold and lock to keep the reading
• 10-inch/250mm aluminium body (around 450g) that stays flat and takes knocks
• Carry storage and a 12-month warranty with UK support

The LEXIVON angle finder is £33.19 inc VAT with free UK delivery and a 30-day returns window, so you can try it against your own work.

Honest limits

The battery needs an occasional change and the display should be kept clean; it reads angles, it does not cut for you. But if you have ever misread a printed scale, the large digital number is exactly the point.

Frequently asked questions

What is a 360 protractor?

A 360 protractor measures the full circle, from 0 to 360 degrees, rather than only the 180 degrees of a standard half-circle protractor. That lets you read reflex and obtuse angles without turning the tool over.

Is a digital angle finder easier to read than a printed protractor?

Yes. A digital angle finder shows the angle as large figures on an LCD, so there is no squinting at fine printed graduations. That is a real help if small scales are hard to see.

Is the LEXIVON angle finder simple to use?

Yes. You open the two arms against the angle, read the number on the display and press to hold it. There are no complicated settings to learn.

Does the LEXIVON angle finder come with a warranty?

The LEXIVON Aluminum Digital Angle Finder is £33.19 and comes with a 12-month warranty and UK support, free UK delivery and a 30-day returns window.
