Submitting Data

Mission

We are on a mission to collect as much community data about BJJ uniforms as possible. The more real-world measurements and reviews we have, the better our recommendations become for everyone. Brand size charts only tell part of the story. Real people’s fit experiences (what worked, what didn’t) fill the gaps and help others avoid bad purchases.

Guide brands

We want to guide brands on providing more sizing data and options. When we can show brands what the community needs (e.g. more size options, clearer measurements), we hope they’ll respond. So we can all get a better, more comfortable fit of clothing. Better data from brands + community input = better fit for everyone.

Real-world data

We want to help brands collect real-world data. Your measurements and reviews, anonymised and aggregated, can inform brands about how their sizes actually fit. Brands can improve their size charts, add new sizes, or adjust cuts based on real feedback, not just guesswork.

Community impact

Every person who adds their real-world measurements will be helping the community as a whole. Your data improves recommendations for others with similar measurements. We encourage you to contribute, even if you’re unsure or only add height and weight. Every bit helps.
