Cons
- Less precise than Starrett or Woodpeckers
- Small blade length limits use on larger panel layout
Best budget precision square. The iGaging double square is significantly better than hardware store squares and acceptable for most furniture woodworking. The budget entry point before investing in Starrett or Woodpeckers accuracy.
Shinwa Sokutei Angle Scribing Square 62081
Shinwa
- ✓Japanese manufactured stainless steel
- ✓Triangular scribing square
- ✓High accuracy
- ✓90 and 45 degree reference edges
Pros
- Japanese manufacturing produces reference accuracy close to Starrett at a lower price
- Stainless steel body resists corrosion better than plain steel squares
- 90 and 45 degree edges are well-calibrated for cut-line scribing and stock squaring
- The practical Starrett alternative for woodworkers who want precision without the Starrett price
Cons
- Less widely available than Starrett in North America
- No sliding head or depth-gauge function like a true combination square
Best Japanese precision square. Shinwa provides near-Starrett accuracy at a noticeably lower price. For woodworkers who want a precision scribing square but cannot justify the full Starrett cost, the Shinwa is the correct intermediate choice.
IRWIN Tools Combination Square, ABS-Body, Blue, 12-Inch (1794470)
Irwin
- ✓12-inch blade
- ✓Combination square
- ✓Mid-range price
- ✓Available at hardware stores
Pros
- 12-inch combination square at an accessible price -- the most practical all-rounder for general woodworking
- Adequate accuracy for furniture and cabinet work that does not require calibration-level precision
- Widely available at hardware stores for quick replacement
- The correct starting combination square before upgrading to Shinwa or Starrett
Cons
- Less precise than Shinwa or Starrett
- Head-lock can slip under heavy use
Best value combination square. The Irwin combination square provides the full combination square function (90, 45, depth gauge, scriber) at the lowest reasonable price. Adequate accuracy for general furniture woodworking. Upgrade to Shinwa or Starrett when precision layout work requires better calibration.
Swanson Tool Co TS149 9 inch Sliding T-Bevel with Brass Bound Hardwood Handle
Swanson
- ✓Adjustable angle
- ✓Brass thumbscrew lock
- ✓Brass-bound hardwood handle
- ✓Stainless steel blade with inch/metric marks
Pros
- Adjustable to any angle -- set from a protractor, transfer to wood, or copy from an existing joint
- Brass thumbscrew lock holds the blade securely once set
- Brass-bound hardwood handle resists wear and looks traditional
- The correct tool for dovetail layout, angled tenons, and any joinery not at 90 or 45 degrees
Cons
- Not a square -- does not verify 90 degrees
- A specialized tool that complements rather than replaces a combination square
Best sliding bevel. The Swanson TS149 is the correct tool for transferring and reproducing non-standard angles in woodworking. Dovetails, angled tenons, and complex geometry all require a sliding bevel. The brass-bound hardwood handle and stainless blade make this a durable shop tool.
An inaccurate square is worse than no square at all. It gives false confidence in a measurement that's actually wrong, and that error compounds through every cut that follows.
The best woodworking squares keep a project true from the first cut through final assembly, whether you're verifying a right angle, marking a line, or setting up a tool before turning it on.
We tested eight squares spanning try squares, combination squares, and speed squares for accuracy, long-term durability, and how easy each was to read on the fly.
The Starrett 11H-12-4R Steel Combination Square led the field at $89.99, with a 9.8 editorial score and a 4.9 rating across nearly 6,800 buyers. Its precision-ground blade is calibrated to 0.001 inch, the same standard that makes Starrett a benchmark in machine shops.
A try square, a combination square, and a speed square each serve a different role, so this guide breaks down which suits marking cut lines, which is best for tool setup, and which travels well for job-site work.
Types of Woodworking Squares
Try square: L-shaped tool with a fixed 90-degree angle between the blade and the handle. Used to check that surfaces and cuts are square. Traditional woodworking square.
Combination square: a try square with a head that slides along the blade. The head includes 90 and 45-degree reference faces and usually a level vial and scriber. The most versatile single square for furniture woodworking.
Speed square: triangular aluminum tool with a 90-degree corner and angled hypotenuse with degree markings. Guides circular saws and jigsaws, marks angled cut lines. Standard for framing and construction.
Sliding bevel (bevel gauge): a square with an adjustable blade locked at any angle. Used to transfer and reproduce non-standard angles.
Checking a Square for Accuracy
All squares (even expensive ones) should be verified for accuracy before use and periodically thereafter.
The 5-cut method for try squares:
- Place the square against a straight reference surface and draw a line
- Flip the square to the other side of the same surface and draw a second line from the same starting point
- If the two lines coincide, the square is accurate at 90 degrees
- Any gap between the lines indicates error -- the error is twice the actual angle deviation
Combination square blade verification:
- Lock the head at a specific position
- Draw a line from the blade
- Flip the square and check whether the blade aligns with the line
- Misalignment indicates the head is not truly at 90 degrees
If a square fails the verification, either adjust (if the square is adjustable) or replace it. An inaccurate square is worse than no square -- it gives false confidence in measurements that are wrong.
Standout: Which Square to Buy First
For most woodworkers setting up a shop:
- First purchase: 7-inch speed square (Swanson or Empire Level) -- $12 to $15
- Second purchase: combination square (Irwin or Shinwa) -- $18 to $55
- Upgrade: Starrett combination square -- $89
- Specialized addition: Woodpeckers precision square for jig work -- $79
In that sequence, the speed square covers guiding circular saw cuts; the combination square handles furniture layout and depth gauging; the Starrett handles precision calibration work.
