YITH Product Size Charts puts sizing answers where sizing doubt lives: on the product page, one click away – custom size tables (chest/waist/inseam per size), assigned per product or category, opening in a popup so customers never leave the purchase flow. Returns from wrong sizing are the apparel industry’s cost center – and sizing uncertainty is the biggest abandonment reason in fashion checkout. A visible, detailed size chart converts the hesitant buyer and cuts the return that follows the guess. Charts support images (measurement diagrams), multiple charts per product (men’s/women’s/kids’), and category-level defaults. Against the WooCommerce family’s conversion tools like YITH Color and Label Variations (variation selection) and return-reducers like YITH Order Tracking, this plugin attacks the sizing-doubt layer specifically.
The 1.5x line maintains steady cadence (registry tracks a single verified version). For apparel, footwear, and fitted-goods catalogs, it’s the cheapest return-reduction available.

Comparison with Competitors
YITH Size Charts vs description-text sizing
| Aspect | YITH Product Size Charts | Sizing in description text |
|---|---|---|
| Visibility | One click, structured | Buried in prose |
| Consistency | Table format | Ad hoc |
| Trust signal | Professional | Careless |
| Return impact | Reduces | Feeds |
Bottom line: Sizing buried in description text forces customers to squint and guess; the structured, accessible chart answers the actual question – and the return it prevents pays for the plugin.
YITH Size Charts vs generic table plugins
| Aspect | YITH Product Size Charts | Generic table plugins |
|---|---|---|
| Workflow | Size-chart-specific | General tables |
| Assignment model | Product/category charts | Per-page embeds |
| Popup UX | Purchase-flow native | Generic modal |
| Price model | GPL license | Varies |
Bottom line: Generic tables render anywhere; YITH’s workflow is sizing-specific – chart assignment, popup placement, apparel-grade UX – the difference between a table and a sizing system.
Recommended Stack – size charts pair with variation UX: combine with YITH Cart Messages so sizing-confident shoppers meet the threshold nudges that raise their order value.

Frequently Asked Questions
How do size charts reduce returns?
Wrong-size returns trace to sizing uncertainty at purchase – the chart answers the question before the buy, converting hesitant customers and preventing the return that follows the guess. Sizing clarity is the apparel industry’s cheapest return-prevention.
Can one product have multiple charts?
Yes – men’s, women’s, and kids’ charts attach to the same product, each selectable – the multi-audience catalog pattern.
Do charts support images?
Yes – measurement diagrams embed alongside tables, showing where to measure, not just the numbers.
Can charts default across a category?
Yes – category-level charts serve product groups (all shirts share a chart), with per-product overrides where items deviate.
Does the chart open without leaving the page?
Yes – popup display keeps customers in the purchase flow: check the chart, close it, continue buying.
