Fashion Metric

MySizeID

Best overall

Neither Fashion Metric nor MySizeID is built for everyday consumers—they are enterprise B2B tools for online clothing retailers. MySizeID wins for smaller e-commerce stores that need a quick, privacy-friendly size recommendation plugin, while Fashion Metric is for large brands with complex sizing needs and dedicated technical teams. The single biggest difference: MySizeID uses phone sensors for measurements (no camera), whereas Fashion Metric predicts size from weight and historical data alone.

Common questions

Can I use Fashion Metric or MySizeID on my phone as a shopper?

No. Both are tools for online retailers, not for consumers. You won't find them in the App Store. MySizeID uses your phone's sensors when you visit a store's website, but there's no standalone app for you to download.

Which tool is easier to set up for a small clothing brand?

MySizeID is much easier. You create a merchant account, install a plugin for Shopify or Magento, upload your size charts, and you're live. Fashion Metric requires a 10-step process with API keys, sandbox testing, and data privacy compliance—overkill for a small store.

Is Fashion Metric better than MySizeID for reducing returns?

Both claim significant return reductions (Fashion Metric doesn't give a number; MySizeID claims up to 30%). Fashion Metric may be more accurate for complex sizing (e.g., custom garments) because it uses historical data and weight, but MySizeID is easier to implement and still effective for standard apparel.

How much do these tools cost?

Neither publishes pricing. MySizeID likely charges a monthly subscription based on store size (typical for e-commerce plugins). Fashion Metric is enterprise-only, meaning you'll need to contact sales and likely pay thousands per month. Neither is free.

Do I need to be technical to use these tools?

MySizeID is beginner-friendly if you use Shopify or Magento—just install a plugin. Fashion Metric requires a developer to handle API integration, data uploads, and A/B testing. If you're not technical, MySizeID is the only realistic choice.

MySizeID wins for small stores needing a quick, no-photo size plugin; Fashion Metric is for big brands with deep pockets and complex sizing needs.

If you run a small-to-medium online clothing store and want a simple, privacy-friendly size recommendation tool that works with Shopify or Magento, go with MySizeID. If you're a large fashion brand with a technical team, complex sizing needs, and a budget for enterprise software, Fashion Metric is worth a look—but expect a longer setup and higher cost.
