Common questions
What is the difference between a speed square and a combination square?
A speed square is a triangular tool used for quick angles and lines. A combination square has a ruler and a sliding head that can be set for angles and depths. It is more versatile.
How do I check if my square is accurate?
Place the square against a straight edge and draw a line. Flip the square and draw another line. If the lines align, it is square. Repeat for best results.
Can I use a square for measuring depth?
Yes, combination squares often have a depth gauge feature. The sliding head can be set to measure the depth of holes or the height of objects.
What is the best square for woodworking?
For fine woodworking, a precision try square or a combination square with high accuracy is best. Woodpeckers and Starrett are highly regarded brands.
Are magnetic squares useful?
Magnetic squares are handy when working with metal studs or steel framing. They allow hands-free operation and are great for plumbing and electrical work.
How should I maintain my square?
Keep your square clean and dry to prevent rust. Lightly oil steel squares. Store them in a protective case or drawer to avoid damage.
Can I use a framing square for small projects?
Yes, but it may be cumbersome. For small tasks, a speed square or combination square is more convenient.
What is a try square?
A try square is a tool used to mark and check 90-degree angles. It typically has a wooden or metal handle and a steel blade.
Which square is best for beginners?
A speed square is great for beginners because it is easy to use and affordable. It handles many tasks without extra features.
Do I need a protractor on a square?
If you often need to measure or mark angles, a square with a protractor is useful. Many speed and combination squares include angle markings.
Our take
For most users, the Swanson Speed Square is the best all-around choice, balancing functionality and cost. If precision is your priority, invest in the Starrett combination square or Woodpeckers precision square. For framing tasks, the Empire framing square is solid.
