Secondly, woodworkers can more precisely measure common 22.5, 30, 45, 60 and 67.5-degree angles than with a standard carpenter square. Just drop the included 1/4″ pin into any of the holes and butt the pin up to the edge of your woodworking piece to mark a precise angle for polygons, squares, hexagons and octagons. 

6. Milwaukee 7-Inch Magnetic Speed Square

The Milwaukee 7-Inch Magnetic Speed Square is good for both woodworking and DIY projects. The laser-etched markings means it can take a beating. It includes standard features like 1/4″ scribing slots for easily ripping lumber. But what sets it apart from other products on the market is its three rare-earth magnets.

11. Woodraphic Precision 8-Inch Square 

Woodraphic precision 8” square

Best uses: Checking for square, marking precise 90-degree lines, laying out joinery lines, measuring, setting saw blade angles

The Woodraphic Precision 8-Inch Square shines in several areas. First, you can easily establish accurate 90-degree lines. The tool is built to meet level 1 Japanese industrial standards. Secondly, there are few marking squares that can so precisely lay out cut lines. This product has marking holes at 1/16″ graduations. But what really stands out is the marking hole sizes themselves. The holes are perfectly fitted for the included 0.5mm mechanical pencil tip with zero wiggle room (read: no margin for error when laying out cut lines). Woodraphic also offers 12-inch, 200mm, and 300mm sizes.

Woodworking squares and their uses

There are six main types of woodworking squares. While nearly all types are great for checking for square, some perform specialty tasks, such as scribing straight and angled lines. Here’s more on each type so you can find the right woodworking square for your project.

Combination squares

Combination squares are one of the most versatile squares to keep in your woodshop. This explains why they’re an essential tool for beginner woodworkers and the first square to put on your shopping list.

Combination squares allow you to strike 45-degree and 90-degree lines with a pencil or marking knife, in addition to checking for square. They include an adjustable knob to lock in a ruler for consistent measurements. Many combination squares also include a bubble level and a removable scratch awl. The most common sizes offered are 6-inch and 12-inch combination squares.

Try squares

Try squares consist of a metal blade attached to a base at a 90 degree angle. Some try square blades are rulers, while others don’t include measurement markings. We think it’s generally best to get a try square with a ruler for the extra versatility to lay out precise lines. This gives you flexibility beyond just checking for square or setting saw blades at 90 degrees. 

Unlike combination squares, try squares don’t have adjustable blades. This limits their overall versatility.

Speed squares 

Speed squares, carpenters squares and rafter squares are all different names for the same tool. A speed square is a triangle-shaped tool that is commonly used in woodworking.

Speed squares are useful for woodworkers to strike 45-degree or 90-degree lines, to measure angles, to use as a circular saw or jigsaw blade guide for 90-degree cuts and to scribe consistent lines.

But speed squares shine beyond just woodworking. Most handyman’s tool belts have a dedicated spot for this tool. It’s rare to complete a project without needing to use a speed square multiple times.

Speed squares come in an array of sizes from 4″ on up to 6″ and 12″.

Double squares

Double squares are a specialty square that combines features of a try square and combination square in one. They consist of an adjustable metal ruler attached to a handle at 90 degrees. Double squares can’t mark 45-degree lines like a combination square.

These hand tools come in handy for checking square, setting up saw blades and locking in the ruler to measure consistent lines. Beyond that, double squares have limited uses in a woodworking shop.

Marking squares

Marking squares are a catch-all category. The common theme that marking squares share is that they all include holes to insert a mechanical pencil tip to scribe consistent lines. Many marking squares come in graduations of 1/32″ and even 1/64″. This explains why they’re used in fine woodworking where precision is critical.

What woodworking squares do you actually need?

Beginner woodworkers will be well prepared for most woodworking projects with a 7-inch or 8-inch speed square and either a 6-inch or 12-inch combination square. 

But it’s important to find a speed square that is built for woodworkers’ needs. The most common speed square available is the Swanson 7″ Speed Square, but it’s not a great fit for woodworkers. The rounded metal edges won’t lay flat on your workpiece, which can lead to inconsistently-measured lines. Hold your pencil or marking knife at different angles, and you’ll get different results

Speed squares, such as the iGaging bench squares we recommend, are specifically designed for woodworking.

Try squares, double squares and marking squares are all nice-to-have tools that will make you more efficient and accurate in the shop. Buy one, and you’ll likely be happy you did. The reality is these are specialty tools that do many of the same things as a combination square or a speed square.

Features of the best woodworking squares

Picking the best woodworking square comes down to squareness, build quality and price. 

First, a good woodworking square needs to be accurate. All of the picks we recommend were tested for squareness that would be required in fine woodworking and measured against a reference ruler for accuracy.

You can check if a square is true by holding the base against a piece of wood and striking a pencil line at 90 degrees. Then flip the square to the other side, line it up to the first line, then strike another line at 90 degrees. The two lines should overlap each other, otherwise your square isn’t truly square.

One reason why a woodworking square is a great beginner’s tool is that you can typically get a good build quality at a low price. In fact, some of our recommended picks are under ten bucks and are dead accurate.

One other item you’ll want to consider is durability, particularly for squares with rulers. Etched markings are generally more durable than stamped markings. That’s not to say stamped markings are bad. It’s more a matter of buying an heirloom-quality tool that’ll last for decades or a choosing high-quality tool with stamped markings that will still last a while with heavy use.

How we tested the picks

We first reviewed popular woodworking sites and forums and read user reviews to narrow down the list of woodworking squares to review in house. After purchasing each, we first tested them all for the squareness that would be required for fine woodworking. Every square we purchased passed this test with flying colors, even the cheap options. Then each square was inspected for build quality by reviewing the quality of the adjustable knob, ease of removal for the scratch awl, ease of slide for the ruler and whether the ruler markings were highly visible or not. Each square was then used in an array of applications to find the best balance of quality and price.
