Cotton socks are the everyday backbone of most sock programs, so the line needs both a sound size system and a small set of construction types that cover nearly all demand. This chart covers the size bands, the three core cotton constructions, and how to assemble them into a starter line that sells through without leaving dead stock in the warehouse.
Sizes in this chart are available through wholesale cotton socks, and every size run can be graded and sampled before bulk production.
Size Bands – S: EU 35–38 – M: EU 39–42 – L: EU 43–46 – XL: EU 47+ Cotton socks are unisex by band. Weight the split to M/L for men’s ranges and M for women’s; add 10% M for household replacement, since the everyday sock is the one most often lost in the laundry. Cotton has less stretch than a synthetic blend, so true-to-size matters more here and a borderline wearer should size up rather than down.
Construction Types – Combed (smooth): the everyday standard; soft, low-pill. Around 60–70% of a line. – Terrycloth (cushioned): looped interior for warmth and comfort; 20–25%, popular in winter and kids. – Ribbed (structured): a 2×2 rib for stay-up and a classic look; 10–15%. Each uses combed cotton yarn; the difference is stitch and cushion. Keeping all three on the same yarn simplifies sourcing and keeps the hand consistent across the line, so a customer who buys a terrycloth pair after a combed pair still recognises the brand.
Length Crew is the cotton default and the volume driver; no-show and ankle cover low shoes; OTC covers boot and cold-weather use. Build crew first and add lengths as demand appears, because crew is the length that works with the widest range of shoes and the fewest fit complaints. We recommend at least one crew SKU per construction type so the size story is complete before the line expands sideways into lengths.
Building the Line A starter cotton line: four core colors × crew combed, plus one terrycloth winter SKU and one ribbed accent. Keep ≤6 colors for shade control, and lock a master for white, which drifts most visibly under both daylight and store lighting. Expand by demand rather than by season, because a tight color set makes reordering cheap and keeps the shade relationship stable across the whole range. As a rule of thumb, one new color should earn its place by outselling the weakest existing color for a full season before it is added to the standing line.
Getting the Size Split Right The split is where a cotton program either sells through or stalls. For a general adult range, weight M and L (roughly 70% combined) and hold S and XL as smaller top-ups. For kids’ lines, size by age band rather than shoe band and expect far more frequent size movement as feet grow. For household multipacks, concentrate on M and L because they serve the widest group of feet in a family. We advise reviewing real sales data after the first season and re-cutting the split, because the first order is a forecast and the second is a fact — and the second is usually where the profit sits.

FAQ
Q: Combed or terrycloth for daily wear? A: Combed for everyday; terrycloth for warmth, winter and kids where cushion is welcome.
Q: How many colors to start? A: Four cores — white, black, grey, navy — then expand by demand rather than all at once.
Q: Crew or ankle for cotton? A: Crew is the volume default; add ankle and no-show once low-shoe demand shows up in the data.
CONCLUSION
Size cotton socks by shoe band and build the line around combed crew, with terrycloth and ribbed as accents and a tight color set for shade control. That structure keeps an everyday program clean, consistent and cheap to reorder — which is where the margin in basic cotton actually lives.
