## Description

Product Description The Swanson Speed Square was first developed by company founder Albert Swanson in 1925. This innovative tool combines 5 tools into 1: 1. Try Square, 2. Miter Square, 3. saw guide, 4. line scriber, and 5. protractor. The Speed Square is die-cast for durability and accuracy. Made of heavy-gauge aerospace aluminum alloy, it is built to last. Black-filled gradations stand out against a matte finish for easy reading. The Speed Square includes the Swanson Blue Book of rafter length and roof construction and also features markings for using the Swanson one-number method of rafter layout. The Swanson Speed Square is our most popular product and remains the most trusted square of its kind. Look for the Diamond cutout for genuine Swanson products. From the Manufacturer The Swanson Tool SO101 7-inch Speed Square is a popular pocket-sized square that incorporates features of the framing square, tri, miter, and protractor squares. Common rafter and hip/valley rafter scales permit one-number references for all cuts. The square is merely rotated to the proper roof pitch value on either scale to assure the correct angle cut. The slot along the scales will accommodate an adjustable locking pin for repetitive cuts using any 1/4-inch bolt and nut. Comes with a handy, 62-page pocket sized booklet that provides vital instructions, reference diagrams, and tables for the construction of roofs and stairs.

Review: The ultimate pocket-sized layout tool - I've owned several speed squares over the years (cheap knockoffs, bigger 12" versions, even some plastic ones), but the Swanson Tool Co. S0101 7 Inch Speed Square (Blue) is still the gold standard — it's the one I reach for almost every single time I need accurate, quick measurements on the jobsite or in my garage. After years of daily use, it's become one of those tools that feels indispensable. Build quality — built like a tank. Made of heavy-gauge aerospace aluminum alloy with a durable blue matte finish. It's tough — won't bend, warp, or rust even after getting banged around in a toolbox, dropped on concrete, or left outside in light weather. The black-filled gradations are sharp and easy to read against the blue background, no fading or wearing off. The edges are crisp for clean scribing, and the lip (heel) is perfectly square for reliable 90° marks. Features & versatility — does way more than a basic square. 7-inch size — compact enough to fit in a pocket or tool pouch, but large enough for most framing, roofing, and layout tasks. Built-in features of a framing square, tri-square, miter square, and protractor. Graduations for common, hip, valley, and jack rafters — perfect for roof pitches and angle cuts. Scribe notches for easy pencil marking. Degree scale for quick angle measurements. Comes with the famous pocket-sized Swanson Blue Book — a mini guide packed with rafter tables, conversion charts, and how-to info for roof framing. Super handy reference right on the tool. What I use it for Marking 90° cuts on lumber Checking square on frames, cabinets, decks Laying out stair stringers and roof rafters Finding angles for trim, brackets, or miter cuts Quick squaring of sheet goods or drywall As a saw guide for circular saws (the lip hooks over the board edge perfectly) Even basic measuring and scribing in tight spaces It's incredibly accurate out of the box — no need to calibrate or second-guess it. The combo of size, durability, and all-in-one functionality makes it perfect for carpenters, woodworkers, DIY homeowners, roofers, remodelers — anyone who builds or fixes things. Value is unbeatable. Usually around $10–15 (often on sale), and it lasts forever. With over 16,000+ reviews averaging around 4.8 stars, it's consistently one of the highest-rated and best-selling carpentry squares on desertcart for good reason. No gimmicks, no plastic parts that break — just a reliable, professional-grade tool at a homeowner price. If you're starting a tool collection, upgrading from a basic combo square, or just want the classic speed square that pros swear by, this Swanson S0101 is the one. It's earned a permanent spot in every tool belt I've owned. Zero complaints — highly recommend! 5 stars all day.

## Questions & Answers

**Q: In what country is this product made?**
A: We proudly make all of our Swanson Speed Squares here in the United States.

**Q: Can you mark 45 degree cuts**
A: Hi Henry,
Absolutely, you can mark 45-degree cuts with our famous Speed Square!  We manufactured it as a right triangle with that use in mind - its hypotenuse (the long side of the triangle) is an exact 45-degree angle.
Thanks for your interest in our square!
The Swnason Team

**Q: Which size (7 or 12) would be best for a re-roofing project?**
A: Typically a framing square would be the most helpful with a roofing project. But if I had to choose one or the other, I guess the 12. While 7 is standard, it will not span the short dimension of the shingle.

**Q: Does the ruler also have units of measurement of centimeters?**
A: Hi Tomer,

Great question!  This Speed Square, our model # S0101, does not include metric units of measurement.  Our Metric Speed Square, model # NA202 (and available on Amazon.com) does  have metric units of measurement.

Hope that helps!
The Swanson Team
