Area per metre width at common spacings
For slab or wall reinforcement specified as “T16@ spacing c/c” — the area provided per unit width at each standard centre-to-centre spacing.
| Spacing | As (mm²/m) |
|---|---|
| T16 @ 100mm c/c | 2011 |
| T16 @ 125mm c/c | 1608 |
| T16 @ 150mm c/c | 1340 |
| T16 @ 175mm c/c | 1149 |
| T16 @ 200mm c/c | 1005 |
| T16 @ 250mm c/c | 804 |
| T16 @ 300mm c/c | 670 |
Equivalent options at 150mm spacing
Every metric bar size at the same reference spacing, so you can see at a glance which other size lands near the same area per unit width as T16.
| Bar | As (mm²/m) |
|---|---|
| T6 | 188 |
| T8 | 335 |
| T10 | 524 |
| T12 | 754 |
| T14 | 1026 |
| T16 (this bar) | 1340 |
| T20 | 2094 |
| T25 | 3272 |
| T28 | 4105 |
| T32 | 5362 |
| T40 | 8378 |
| T50 | 13090 |
Area and mass are computed directly from the nominal diameter (mass assumes standard steel density, 7850 kg/m³) — the same values the Rebar Calculator uses.
