An LR6 can hold up to 1,900 Void Traces. That matches the cap implied by community references for LR6 and the mastery-based storage scaling.

Quick Scoop

Void Trace storage in Warframe scales with Mastery Rank, so higher ranks hold more. For LR6, the cap is 1,900.

Why this matters

If you’re farming relics, hitting the cap means extra traces won’t be kept until you spend some. A common habit is to spend traces on relics before opening more to avoid wasting rewards.

Some older posts describe a formula tied to Mastery Rank, but the LR6 number above is the practical answer people are using now.
