Smart Size Charts · Centralized sizing data

Every size chart,
in one place.

Centralize your sizing data, build charts or start from our library, and assign them across your whole catalogue - footwear and apparel - in clicks. Dynamic, per-style and always in sync, without the spreadsheet sprawl.

The size-chart trap

Every retailer picks a spot on this line.

Easy to run
Accurate
The left end · one chart for everything

Easy to run. Wrong for half the catalogue.

Simple to maintain - but different styles fit differently, so shoppers get numbers that don't match what they're buying. Returns follow.

Wrong sizing data
The right end · a chart per style

Accurate. And a maintenance burden.

Right for every style, but someone has to build, assign and keep every chart current - and it quietly slips out of date.

Heavy to maintain
Smart Size Charts
Easy to run and accurate.

Both ends of the line, at once - centralize the charts, and the trade-off disappears.

On your product pages

A chart shoppers actually read.

Right on the product page, in the shopper’s own units, specific to the style in front of them - with the fit guidance a static theme chart can’t carry. Try the cm ⇄ in toggle: the chart converts live.

Why it works

Set your charts once.
Right everywhere, always.

01
One source of truth

Every chart lives in one place. Update it once and it's live across every product it's assigned to - no stale numbers hiding in the catalogue.

02
Dynamic by style

Charts adapt per product and carry fit notes where they help - footwear and apparel, each sized on its own terms rather than one blanket table.

03
Still part of the journey

Some shoppers want a recommendation; others trust the chart. StrutFit makes both first-class, so every shopper sizes up with confidence.

For your team

Make a chart in minutes - or take one off the shelf.

No spreadsheets, no theme edits, no developer ticket. Two ways in, and either way the chart is live on every product it covers - update it once and it’s current everywhere.

Build your own
From blank to live in minutes.

Set your values, add a fit note where it helps, assign it to a whole collection. Done - it’s on every product page it belongs to.

Or start from the library
Ready-made charts, off the shelf.

A library of pre-built size charts for the standards your shoppers already know. Pick one, tweak it if you like, assign it - minutes, not weeks.

Dynamic, per-style, with fit notes.

A chart that adapts to each style, footwear or apparel - and carries extra guidance where it helps, like ‘runs small’ or ‘relaxed fit’, so shoppers choose with confidence.
