What Size T Square Is Right for Your Project?

One of the essential tools for anyone who is working with drafting, woodworking, or even metalworking is a T-square. This simple, non power tool, is something that can help you make your plans for that next building, special part you need, or creating a product to sell. It is a straight edge that is shaped in the form of a 'T'. One end is used for creating straight lines, while the other glides along the edge of a table or workbench. 

Creating Blueprints

The only task of a T-square is to aid in the drafting of blueprints. While you can use a ruler, it is not going to give true lines that are going to be parallel to others within the plain. A T-square alleviates this problem by sliding on a fixed point (the edge of the drafting table) so all lines are straight and true according to the plain it is on. 

Size Corresponds to Need

As you can guess, T-squares come in a lot of different sizes. The size that you need for your project is going to be determined by two things.

  • Size of table - If you have a small workspace then you are not going to need a larger T-square. By rule, the T-square should not extend past the actual drawing surface. 
  • Size of project - If you are going to fashion a small replacement part for a tool, you are not going to need a T-square that is the size of one you need to create full size blueprints of a garage. Smaller T-squares help with detail work that is involved in smaller projects.
