How to Use Amazon's Fit Insights Tool to Reduce Apparel Returns
Amazon's Fit Insights tool uses AI to analyze returns data, customer reviews, and size charts for apparel and shoe brands, helping sellers identify and fix size and fit issues that drive returns.
Overview
Amazon's Fit Insights tool is an AI-powered analytics feature designed to help apparel and shoe sellers diagnose and fix size and fit problems that drive returns. Available exclusively to brands enrolled in Amazon Brand Registry, the tool pulls together returns data, customer reviews, and size chart analysis to give sellers a clear picture of why customers are sending products back — and what to do about it.
Key Points / What Sellers Need to Know
- Brand Registry required — Fit Insights is only available to sellers with brands registered in Amazon Brand Registry, and account administrators must grant specific permissions for access.
- Sales history needed — Products must have shipped units within the last 12 months to appear in the tool. New or dormant listings won't generate data.
- Return health scoring — Every parent ASIN receives a color-coded return health rating (from green to red) benchmarked against similar products in the same department and product type.
- Four analysis modules — The tool includes a dashboard overview, return analysis, review sentiment analysis, and a size chart analyzer, each offering distinct insights.
- Actionable at the size level — Return analysis breaks down problems by individual size, so sellers can pinpoint exactly which sizes are causing the most returns.
How Return Health Scoring Works
The Fit Insights dashboard aggregates your brand's listings at the parent ASIN level and assigns each one a return health score. This score is relative, meaning it compares your product's return rate against other ASINs in the same department and product type rather than using a fixed threshold. Products are rated on a five-tier scale: excellent (green) for products significantly outperforming peers, good (light green) for above-average performers, fair (yellow) for products in line with category norms, poor (orange) for underperformers, and very poor (red) for products with significantly elevated return rates. Sellers can filter the dashboard by return health status, department, or order volume, and can flag critical ASINs for ongoing monitoring.

Analysis & Recommendations
Why This Matters
Fit-related returns are one of the largest controllable costs for apparel sellers. This tool provides data-driven insights to reduce return rates, protect margins, and improve customer satisfaction.
Key Takeaways
- Return health is scored relative to category peers on a five-tier scale, helping sellers prioritize which ASINs need attention most
- Return analysis breaks down issues by individual size, enabling targeted fixes rather than broad listing overhauls
- Review sentiment analysis flags fit and quality complaints that appear more often than in competing products
- Size chart consistency across all listing surfaces (tool, images, A+ content) is critical for reducing confusion-driven returns
Recommended Actions
- →Review your Fit Insights dashboard regularly and prioritize ASINs with poor or very poor return health for immediate listing and size chart updates
- →Audit your size charts using the analyzer and ensure body measurements, units, and values are complete and consistent across all listing surfaces
- →Use review sentiment insights to update product descriptions with more accurate sizing guidance where customers report recurring fit issues
