Description

Big Boot Media Product Size Chart & Fit Finder adds clickable size buttons, a size chart, a size guide and a Find Your Fit recommendation modal to WooCommerce variable product pages. Store owners can configure a chest measurement size chart and fit adjustments. The customer-facing interface uses neutral branding and does not advertise Big Boot Media or The Basic Cotton.

The existing WooCommerce variation dropdown remains available to WooCommerce’s variation logic, while the size buttons provide a more visual selection interface. Designed for clothing sized using chest measurements.

Upgrade from The Basic Cotton Fit Assistant

On activation, if the new plugin has no saved settings, it copies the earlier plugin’s tbcfa_settings option into bbmfa_settings. Existing size charts, fit offsets and custom labels are retained. The former default heading “Find Your Basic Cotton Fit” is replaced with “Find Your Fit”, and a neutral “SIZE & FIT” eyebrow is used by default. The original settings option is not deleted.

Do not run both plugins at once. If the original plugin remains active, Size Chart & Fit Finder does not load its own front-end assets and displays an admin warning.

Default size chart

XS|36
S|38
M|40
L|42
XL|44
XXL|46

How recommendations work

The customer enters a chest measurement in inches or centimetres and chooses Fitted, Regular or Relaxed. The plugin applies the configured adjustment and suggests the nearest size. Defaults are -2 inches for Fitted, 0 for Regular and +2 for Relaxed. Recommendations are general sizing aids, not guarantees. Review the settings to match your products.

Notes

Front-end assets load only on variable WooCommerce product pages.
The native WooCommerce variation selector remains for stock and Add to Cart logic.
No third-party API, AI service or subscription is required.
No theme files are modified.
