For this post, I have put together a collection of the best T-Square rulers available for purchase.
UPDATED: June 4, 2021.
Along with a drafting table, board, pencil, and chair, a T-square is a must-have item for technical hand drawing. As an architecture student, this basic tool was one of my first purchases.
While the world has mostly moved to software for advanced drafting, the T-square is still an essential tool for drafting by hand.
I have included a range of lengths and materials so you are able to find exactly what you are looking for. The metal rulers will last longer and are more durable, but are more expensive than the plastic options.
Pro tip: if you will be using it as a cutting edge, go with a metal ruler instead of plastic, this will prevent ruining it with your knife.
So here is my list of The Best T-Square Rulers for 2021.
Enjoy!
