Bouldering grades
Boulders are graded with numbers from 1 (easiest, 'a ladder up the wall') to 9 (hardest), plus a wildcard grade. 'Lab Experiment' and competition tags mark ungraded boulders. Boulder Lab doesn't publish V-grade equivalents, so the ranges below are our estimate, spreading the nine numbers over a typical VB–V10 range in order.
| Level | V-scale | ≈ Font |
|---|---|---|
| 1 | VB–V0 | 3–4B+ |
| 2 | V0–V1 | 4B–5B |
| 3 | V1–V2 | 5A–5C |
| 4 | V2–V3 | 5B–6A+ |
| 5 | V3–V4 | 5C+–6B+ |
| 6 | V4–V5 | 6A+–6C+ |
| 7 | V5–V6 | 6C–7A |
| 8 | V6–V8 | 6C+–7B+ |
| 9 | ≥ V8 | ≥ 7B |

Boulder Lab grades the same way at all 3 of its gyms. All Boulder Lab gyms and grades
Estimated by Gear Loop. The gym publishes only the order of its colours, so these ranges are our best guess from its chart and climbers' descriptions. Gyms reset and regrade often, and grades vary between setters, so treat this as a guide and check the boards when you visit.
