AR.1
Tapered header
| Type No. | A | B | C | D | Dimension | No. of whole bricks | No of bricks in semi-circle |
| AR 1.1 | 215 | 102 | 75 | 59 | 910 | 4 | 20 or 21 |
| AR 1.2 | 215 | 102 | 75 | 64 | 1360 | 6 | 28 or 29 |

| AR 1.4 | 215 | 102 | 75 | 69 | 2710 | 12 | 53 or 54 |
Note: Although AR1 can be used for other than ideal spans by varying the number of bricks, tapered headers are frequently made to dimensions other than above. AR2 is less versatile because the longer voussoir joint accentuates splays.
