Estimate a realistic conventional deadlift range from your RDL performance, with confidence scoring and practical coaching interpretation.

For dumbbells, enter total combined load from both hands.

Grip limitation on conventional?
This tool estimates a range, not an exact conversion. Strict lower-rep barbell RDL inputs are usually more informative.
Use this to estimate a realistic conventional deadlift range and identify likely bottlenecks.

Core concept
Both lifts are related, but conventional deadlift expression depends on setup, floor break, bracing, and skill quality.
A strong RDL often reflects useful posterior-chain strength, especially hinge control and hip extension under load. But conventional deadlift performance depends on more than hinge strength alone: start position mechanics, force from the floor, bracing, grip, and bar path consistency all change outcomes [1][2][4].
That is why this calculator outputs a low-best-high range and confidence band instead of one exact deadlift number.

Use this as planning context and bottleneck diagnosis support, not as a guaranteed max prediction.
How to use
Fast process for range estimation and training decisions.
Use a strict set with clear hinge mechanics. Add RPE when possible to improve estimate quality.
Use the low-best-high range as a planning band, not a guaranteed conversion number.
Compare your actual conventional pull (optional) to identify likely technique or accessory bottlenecks.
