The models on this wiki have various different weight classes according to their peak weight:
| Class | Weight range |
|---|---|
| Chubby | 150-200lbs. |
| BBW | 200-350lbs. |
| SSBBW | 350-600lbs. |
| USSBBW | 600+lbs. |
| Immobility | N/A |
These weight ranges are an estimate, see each individual page for more information.
Some models lose weight, either from dieting, exercise, weight loss surgery, or a combination of the three. We try to document both their last known weight and peak weight (given they differ from each other).
