Measure your stock, or use the steel angle pages (aisc-l-angles, en-10056 angles) where the radii are printed.\n- Dimensions are legs a x b x thickness in inches, with the mm conversion.\n\ntype  size a x b x t (in)  lb/ft  area (in2)  a (mm)  b (mm)  t (mm)\nequal  0.75 x 0.75 x 0.125  0.203  0.173  19.0  19.0  3.17\nequal  1 x 1 x 0.125  0.277  0.235  25.4  25.4  3.17\nequal  1 x 1 x 0.188  0.401  0.341  25.4  25.4  4.78\nequal  1 x 1 x 0.25  0.515  0.438  25.4  25.4  6.35\nequal  1.25 x 1.25 x 0.125  0.35  0.298  31.8  31.8  3.17\nequal  1.25 x 1.25 x 0.188  0.511  0.434  31.8  31.8  4.78\nequal  1.25 x 1.25 x 0.25  0.662  0.563  31.8  31.8  6.35\nequal  1.5 x 1.5 x 0.125  0.424  0.36  38.1  38.1  3.17\nequal  1.5 x 1.5 x 0.188  0.621  0.528  38.1  38.1  4.78\nequal  1.5 x 1.5 x 0.25  0.809  0.688  38.1  38.1  6.35\nequal  1.75 x 1.75 x 0.125  0.497  0.423  44.4  44.4  3.17\nequal  1.75 x 1.75 x 0.188  0.731  0.622  44.4  44.4  4.78\nequal  1.75 x 1.75 x 0.25  0.956  0.813  44.4  44.4  6.35\nequal  2 x 2 x 0.125  0.578  0.491  50.8  50.8  3.17\nequal  2 x 2 x 0.188  0.848  0.721  50.8  50.8  4.78\nequal  2 x 2 x 0.25  1.11  0.944  50.8  50.8  6.35\nequal  2 x 2 x 0.313  1.363  1.159  50.8  50.8  7.95\nequal  2 x 2 x 0.375  1.607  1.366  50.8  50.8  9.52\nequal  2.5 x 2.5 x 0.188  1.069  0.909  63.5  63.5  4.78\nequal  2.5 x 2.5 x 0.25  1.404  1.194  63.5  63.5  6.35\nequal  2.5 x 2.5 x 0.313  1.73  1.472  63.5  63.5  7.95\nequal  2.5 x 2.5 x 0.375  2.048  1.741  63.5  63.5  9.52\nequal  3 x 3 x 0.188  1.275  1.084  76.2  76.2  4.78\nequal  3 x 3 x 0.25  1.684  1.432  76.2  76.2  6.35\nequal  3 x 3 x 0.313  2.083  1.771  76.2  76.2  7.95\nequal  3 x 3 x 0.375  2.474  2.104  76.2  76.2  9.52\nequal  3 x 3 x 0.5  3.227  2.744  76.2  76.2  12.7\nequal  3.5 x 3.5 x 0.25  1.988  1.691  88.9  88.9  6.35\nequal  3.5 x 3.5 x 0.375  2.926  2.488  88.9  88.9  9.52\nequal  3.5 x 3.5 x 0.5  3.826  3.253  88.9  88.9  12.7\nequal  4 x 4 x 0.25  2.282  1.941  101.6  101.6  6.35\nequal  4 x 4 x 0.375  3.367  2.863  101.6  101.6  9.52\nequal  4 x 4 x 0.5  4.414  3.753  101.6  101.6  12.7\nequal  5 x 5 x 0.375  4.238  3.603  127.0  127.0  9.52\nequal  6 x 6 x 0.375  5.119  4.353  152.4  152.4  9.52\nequal  6 x 6 x 0.5  6.754  5.743  152.4  152.4  12.7\nequal  8 x 8 x 0.5  9.142  7.773  203.2  203.2  12.7\nunequal  1.5 x 1.25 x 0.125  0.386  0.329  38.1  31.8  3.17\nunequal  1.5 x 1.25 x 0.188  0.566  0.481  38.1  31.8  4.78\nunequal  1.75 x 1.25 x 0.125  0.423  0.36  44.4  31.8  3.17\nunequal  2 x 1.5 x 0.125  0.497  0.423  50.8  38.1  3.17\nunequal  2 x 1.5 x 0.188  0.731  0.622  50.8  38.1  4.78\nunequal  2 x 1.5 x 0.25  0.956  0.813  50.8  38.1  6.35\nunequal  2.5 x 1.5 x 0.188  0.848  0.721  63.5  38.1  4.78\nunequal  2.5 x 2 x 0.188  0.959  0.815  63.5  50.8  4.78\nunequal  2.5 x 2 x 0.25  1.257  1.069  63.5  50.8  6.35\nunequal  3 x 1.5 x 0.25  1.266  1.077  76.2  38.1  6.35\nunequal  3 x 2 x 0.188  1.068  0.908  76.2  50.8  4.78\nunequal  3 x 2 x 0.25  1.403  1.193  76.2  50.8  6.35\nunequal  3 x 2 x 0.375  2.047  1.74  76.2  50.8  9.52\nunequal  3 x 2.5 x 0.25  1.55  1.318  76.2  63.5  6.35\nunequal  3.5 x 2.5 x 0.25  1.684  1.432  88.9  63.5  6.35\nunequal  4 x 3 x 0.25  1.988  1.691  101.6  76.2  6.35\nunequal  4 x 3 x 0.375  2.926  2.488  101.6  76.2  9.52\nunequal  5 x 3 x 0.25  2.265  1.926  127.0  76.2  6.35\nunequal  5 x 3 x 0.375  3.349  2.848  127.0  76.2  9.52\nunequal  5 x 3.5 x 0.5  4.703  3.999  127.0  88.9  12.7\nunequal  6 x 4 x 0.375  4.237  3.603  152.4  101.6  9.52\nunequal  6 x 4 x 0.5  5.578  4.743  152.4  101.6  12.7\n\nFiles elsewhere (not hosted by Xem Studio; license as stated by the publisher):\n- 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\n- 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\n\nNo true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.\nAPI: https://xemstudio.com/api/geometry?object=aluminum-angles\n",
