Quick take
When you are choosing a measuring layout tool, the first question is what kind of lines you will be making. A compact folding L-shaped square is handy when you need to lock into stepped angles. A multi-angle template ruler is made for copying angles that already exist in a room or on a piece of material. A general carpenter square gauge covers basic woodworking and construction marks. A 16-by-24-inch steel framing square is the big-surface tool for rafter and roof layout.
In this set, the listed prices run from USD 23.98 for the 12in folding carpenter square to USD 10.49 for the orange carpenter square gauge. That leaves a USD 13.49 difference between the two ends, so the real deciding factor is job fit rather than price alone.

Product notes
12in Folding Carpenter Square L Shape Angle Measuring Ruler Framing Layout Tool
If repeated angle settings are part of your work, this folding L-shaped square earns its place at the top of the price list. Its rotating design adjusts in 15° steps, so you can set an angle and keep it there for multiple marks. The tool combines an aluminum alloy body with a stainless steel ruler, and it has dual-sided metric/imperial scales, a scribing pin for layout lines, and a reinforced support screw for holding the square against the workpiece. The tradeoff is its compact 12in reach: it is portable and convenient, but it will not span the large layouts that a 16-by-24-inch framing square can cover.
for Woodworking, Crafting, Construction, Flooring Multi Angle Measuring Ruler
This yellow measuring ruler works as a universal angle template, which makes it the practical choice when you need to duplicate an angle that already exists. You loosen the screws, slide the ruler to match the angle, then use it to draw or mark the same angle on the next piece. The one-handed design and lightweight 0.31-pound body make it easy to hold while you mark. It is indexed in both standard and imperial scale, so you can read the angle after it is set. The main limitation is that this is a template-style tool rather than a long steel square; for full-length wall or rafter lines, the 16-by-24-inch steel framing square in this comparison is the larger option.
Carpenter Square Measuring Tool Woodworking Gauge Construction Layout Tool
This orange gauge is the straightforward, all-around carpenter square in the set. It is intended for measuring angles, aligning materials, and marking accurate cutting lines across woodworking, carpentry, construction, tile, and DIY tasks. Its simple design keeps the layout job moving without the added mechanical detail of an adjustable angle lock. It is not the most specialized pick, though: the yellow multi-angle ruler is built for copying existing angles, and the 16-by-24-inch steel framing square is the one with the larger layout surface and rafter tables. Use this orange carpenter square when you need a simple go-to marker for everyday layout.
Rafter Framing Square 16 X 24 Inches Steel Construction Layout Measuring Tool
This steel framing square is the heavy-duty option for larger layout fields. Its 16-by-24-inch footprint gives you a long straightedge to work with, and the inch and metric scales cover both measuring systems. It also includes framing and rafter tables, so roof calculations can stay on the tool while you mark. That combination makes this square a strong reason to pick it when your projects involve walls, rafters, or floor framing. The tradeoff is flexibility: the 12in folding carpenter square handles custom angle settings more directly. This framing square is best when a long steel edge and table-assisted roof math are more important than adjustability.
