Winch Sizing Calculator
Find the minimum rated winch for your vehicle weight and recovery scenario.
Units:
GVW = curb weight + passengers + gear + fuel
Quick presets:

Using a snatch block(doubles mechanical advantage, halves required winch rating)
Vehicle GVW
5,000 lb
Pull Required
7,500 lb
Min Winch Rating
11,250 lb
Wire Rope Pull by Drum Layer
Rated pull is at layer 1. Keep rope nearly fully deployed for maximum pull.
| Layer | % of Rated Pull | Effective (10K winch) |
|---|---|---|
| 1 (fully deployed) | 100% | 10,000 lb |
| 2 | 86% | 8,600 lb |
| 3 | 74% | 7,400 lb |
| 4 | 65% | 6,500 lb |
Wire vs Synthetic Rope
Wire Rope (6×19)
+ Durable, abrasion resistant, cheaper
− Heavy, can kink, dangerous if it snaps, rusts
Synthetic (UHMWPE)
+ Lightweight, safe if breaks (falls not whips), easy to handle
− Susceptible to UV/abrasion, more expensive, inspect regularly

General rule: winch rating ≥ 1.5× GVW. Always use a winch dampener on wire rope and never stand in the pull line.
