About SizeHub

What SizeHub Is

SizeHub is a reference site for clothing and shoe sizing. Clothing sizes are not standardised: a medium at one brand can measure two or three inches wider in the chest than a medium at another, and the same shoe length is labelled differently in US, UK and EU systems. The result is that people order the wrong size, wait for delivery, and then have to return the item. SizeHub exists to remove that guesswork by putting each brand's own size chart, in both inches and centimetres, on a single page that loads quickly on a phone, alongside converters that translate a size you already know into the system a shop is using.

The site is free, has no login, and does not sell anything itself. Where a page links out to a retailer, that link is marked and disclosed. Nothing about which brands we cover or what we say about their fit depends on those links.

Where Our Size Data Comes From

Every size chart on SizeHub begins with the brand's own published size guide. For each brand we locate the size guide on the brand's official website — usually linked from a product page, a "size guide" or "fit guide" link near the size selector, or the customer-service section of the site. Where a brand publishes different guides for different regions or product lines, we use the guide that matches the market and garment type the page covers, and note the region in the chart.

Measurements are then transcribed into our chart tables exactly as the brand states them: the same body or garment measurement, the same size labels, and the same units. When a brand publishes only one unit system, we convert to the other (1 inch = 2.54 cm) and round to the precision the brand itself uses, so the numbers you compare across brands are directly comparable. We do not average brands together, invent intermediate sizes, or fill gaps a brand leaves blank.

How Often We Re-check the Charts

Charts are reviewed on a quarterly cadence. A review means re-opening the brand's current published size guide and comparing it line by line against what we have on the page. Each brand page shows the period of its most recent review near the size chart, so you can see how current the figures are.

When a brand changes its sizing — new measurements, renamed size labels, a discontinued fit, or a switch to a different regional standard — we update the chart outside the quarterly cycle, adjust any fit notes that referenced the old numbers, and refresh the review date. If a brand removes its size guide entirely and we can no longer verify the figures, we say so on the page rather than leaving unverifiable numbers in place.

What Our Fit Notes Are

Alongside the raw chart, most brand pages carry short fit notes. These are editorial observations, not measurements. They are written by comparing one brand's published numbers against another's at the same nominal size, reading the brand's own descriptions of a cut (slim, relaxed, oversized, athletic), and taking account of widely reported fit patterns from customer reviews and returns commentary.

The distinction matters. The chart is what the brand states and can be checked against the brand's site. A fit note is our interpretation of what those numbers mean in practice — for example, that a brand's "regular" trouser runs closer to another brand's slim. Where a fit note is a judgement call, it is phrased as one. If the two ever disagree, trust the chart and your own measurements.

Reporting an Error

If a chart does not match what a brand currently publishes, or a fit note does not match your experience, please tell us. Use the contact form and include the brand, the page, and the correct figure or the link to the brand's size guide if you have it. Corrections are checked against the brand's published guide and, when confirmed, applied to the page along with an updated review date.
