Ranked by median difficulty, easiest first. The bar is a range, not a label — a channel typically spans a wide stretch of the scale, so one level would be false for its own hardest videos.
| # | Channel | Level range (0–100) | Median | Typical band | Pace | Videos | Hours |
|---|---|---|---|---|---|---|---|
| 1 | Easy English | 6–48 | 31 | B1-B2 | medium | 138 | 37 h |
| 2 | BBC Learning English | 0–75 | 54 | B2-C2 | medium | 191 | 30 h |
| 3 | Speak English With Vanessa | 28–85 | 56 | B1-B2 | fast | 174 | 85 h |
| 4 | Learn English with Bob the Canadian | 43–86 | 66 | B1-B2 | fast | 88 | 34 h |
3 of these 4 channels carry the same vocabulary band (B1-B2), and their scores still run from 0 to 86. That gap is pace: what separates the easiest of these channels from the hardest is how fast people talk, not which words they use. How that is measured →
