Qualities to Look for When Buying a Speed Square

Here are the features which separate an excellent speeding square. Keeping an eye out for these qualities will undoubtedly ensure the perfect speed square for you.


Ironically, most tools of this category are not proper squares. The angling is off slightly. Be sure to ensure that the angles of the devices are 45 degrees and 90 degrees. One of the prime functions of such a product is the determination of angle.

Therefore, buying a tool with the angles all messed up is a big no-no and can make the entire purchase a massive loss.


Now, this is a factor that depends entirely on the person who's buying the product. If you're someone who does carpentry as a hobby, then a 7"-8" tool should do the job for you. They are pretty easy to carry and usually lighter in weight.

However, if you're in the construction business or manufacture large-scale wooden products, then a 12" device is what you should look to purchase. I mean, sure, they might be challenging to carry around, but it's not like you'd be taking them out of your construction site or workshop, to begin with.

Build Material

Considering how one uses such tools to construct wooden objects, and you will often find them in cluttered environments with other heavy-set tools, it's best to ensure a sturdy product. Therefore, the build quality is one factor that you should not compromise under any circumstances.

It's best to buy speed squares made with aluminum alloy as they are near impossible to break or damage. Pair that up with anti-rust and weather-resistant features for the best output.
