Aluminum angles (equal and unequal leg): 1 x 1 x 1/8, 2 x 2 x 1/4, 3 x 3 x 1/4, 4 x 3 x 3/8 sizes and weights — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/aluminum-angles/ (sheet CC BY 4.0) Basis: Aluminum Association Standard Structural Profiles 2020 (ASTM B308 angles): leg sizes, weight and area; numbers only Catalog version: 2026-10-20 Sizes: see table below - Aluminum Association standard angles (ASTM B308 extruded 6061): the sizes below are the equal-leg and unequal-leg angles with weight per foot and cross-section area. - No file is published: the fillet and toe radii of the angle profiles are not printed in any table we could read (the sources list sizes, weight and area only), and Xem does not publish a radius that is not printed. Measure your stock, or use the steel angle pages (aisc-l-angles, en-10056 angles) where the radii are printed. - Dimensions are legs a x b x thickness in inches, with the mm conversion. type size a x b x t (in) lb/ft area (in2) a (mm) b (mm) t (mm) equal 0.75 x 0.75 x 0.125 0.203 0.173 19.0 19.0 3.17 equal 1 x 1 x 0.125 0.277 0.235 25.4 25.4 3.17 equal 1 x 1 x 0.188 0.401 0.341 25.4 25.4 4.78 equal 1 x 1 x 0.25 0.515 0.438 25.4 25.4 6.35 equal 1.25 x 1.25 x 0.125 0.35 0.298 31.8 31.8 3.17 equal 1.25 x 1.25 x 0.188 0.511 0.434 31.8 31.8 4.78 equal 1.25 x 1.25 x 0.25 0.662 0.563 31.8 31.8 6.35 equal 1.5 x 1.5 x 0.125 0.424 0.36 38.1 38.1 3.17 equal 1.5 x 1.5 x 0.188 0.621 0.528 38.1 38.1 4.78 equal 1.5 x 1.5 x 0.25 0.809 0.688 38.1 38.1 6.35 equal 1.75 x 1.75 x 0.125 0.497 0.423 44.4 44.4 3.17 equal 1.75 x 1.75 x 0.188 0.731 0.622 44.4 44.4 4.78 equal 1.75 x 1.75 x 0.25 0.956 0.813 44.4 44.4 6.35 equal 2 x 2 x 0.125 0.578 0.491 50.8 50.8 3.17 equal 2 x 2 x 0.188 0.848 0.721 50.8 50.8 4.78 equal 2 x 2 x 0.25 1.11 0.944 50.8 50.8 6.35 equal 2 x 2 x 0.313 1.363 1.159 50.8 50.8 7.95 equal 2 x 2 x 0.375 1.607 1.366 50.8 50.8 9.52 equal 2.5 x 2.5 x 0.188 1.069 0.909 63.5 63.5 4.78 equal 2.5 x 2.5 x 0.25 1.404 1.194 63.5 63.5 6.35 equal 2.5 x 2.5 x 0.313 1.73 1.472 63.5 63.5 7.95 equal 2.5 x 2.5 x 0.375 2.048 1.741 63.5 63.5 9.52 equal 3 x 3 x 0.188 1.275 1.084 76.2 76.2 4.78 equal 3 x 3 x 0.25 1.684 1.432 76.2 76.2 6.35 equal 3 x 3 x 0.313 2.083 1.771 76.2 76.2 7.95 equal 3 x 3 x 0.375 2.474 2.104 76.2 76.2 9.52 equal 3 x 3 x 0.5 3.227 2.744 76.2 76.2 12.7 equal 3.5 x 3.5 x 0.25 1.988 1.691 88.9 88.9 6.35 equal 3.5 x 3.5 x 0.375 2.926 2.488 88.9 88.9 9.52 equal 3.5 x 3.5 x 0.5 3.826 3.253 88.9 88.9 12.7 equal 4 x 4 x 0.25 2.282 1.941 101.6 101.6 6.35 equal 4 x 4 x 0.375 3.367 2.863 101.6 101.6 9.52 equal 4 x 4 x 0.5 4.414 3.753 101.6 101.6 12.7 equal 5 x 5 x 0.375 4.238 3.603 127.0 127.0 9.52 equal 6 x 6 x 0.375 5.119 4.353 152.4 152.4 9.52 equal 6 x 6 x 0.5 6.754 5.743 152.4 152.4 12.7 equal 8 x 8 x 0.5 9.142 7.773 203.2 203.2 12.7 unequal 1.5 x 1.25 x 0.125 0.386 0.329 38.1 31.8 3.17 unequal 1.5 x 1.25 x 0.188 0.566 0.481 38.1 31.8 4.78 unequal 1.75 x 1.25 x 0.125 0.423 0.36 44.4 31.8 3.17 unequal 2 x 1.5 x 0.125 0.497 0.423 50.8 38.1 3.17 unequal 2 x 1.5 x 0.188 0.731 0.622 50.8 38.1 4.78 unequal 2 x 1.5 x 0.25 0.956 0.813 50.8 38.1 6.35 unequal 2.5 x 1.5 x 0.188 0.848 0.721 63.5 38.1 4.78 unequal 2.5 x 2 x 0.188 0.959 0.815 63.5 50.8 4.78 unequal 2.5 x 2 x 0.25 1.257 1.069 63.5 50.8 6.35 unequal 3 x 1.5 x 0.25 1.266 1.077 76.2 38.1 6.35 unequal 3 x 2 x 0.188 1.068 0.908 76.2 50.8 4.78 unequal 3 x 2 x 0.25 1.403 1.193 76.2 50.8 6.35 unequal 3 x 2 x 0.375 2.047 1.74 76.2 50.8 9.52 unequal 3 x 2.5 x 0.25 1.55 1.318 76.2 63.5 6.35 unequal 3.5 x 2.5 x 0.25 1.684 1.432 88.9 63.5 6.35 unequal 4 x 3 x 0.25 1.988 1.691 101.6 76.2 6.35 unequal 4 x 3 x 0.375 2.926 2.488 101.6 76.2 9.52 unequal 5 x 3 x 0.25 2.265 1.926 127.0 76.2 6.35 unequal 5 x 3 x 0.375 3.349 2.848 127.0 76.2 9.52 unequal 5 x 3.5 x 0.5 4.703 3.999 127.0 88.9 12.7 unequal 6 x 4 x 0.375 4.237 3.603 152.4 101.6 9.52 unequal 6 x 4 x 0.5 5.578 4.743 152.4 101.6 12.7 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Engineers Edge: ASTM B308 aluminum angle, equal leg (Aluminum Association Standard Structural Profiles 2020): size, weight, area — web — Publisher's page; dimensions are facts — https://ns1.engineersedge.com/angle_aluminum.htm - Engineers Edge: ASTM B308 aluminum angle, unequal legs: size, weight, area — web — Publisher's page; dimensions are facts — https://ns1.engineersedge.com/angle_unequal.htm No true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.
