Leggings Inseam Lengths: 7/8 vs Full vs Biker, Settled

The chart

Why 7/8 became the default

Three practical reasons: it flatters (showing the ankle lengthens the leg line), it travels across heights (on shorter customers a 7/8 wears as a clean full length instead of bunching), and it photographs better with trainers. Most premium lines now cut their hero legging as a 7/8 and offer full length as the second option rather than the first.

Height changes the story

Inseam labels assume an average-height fit model; on a 155 cm customer a 71 cm full length pools at the ankle, and on a 180 cm customer a 7/8 becomes a capri. The honest fixes are stating garment inseam in cm on the size chart (not just “7/8”), and — once volume justifies it — offering the hero style in two inseams. Length grading between sizes is small (±1–1.5 cm per size); the full logic is in sizing & grading.

Length is a knitting decision in seamless

On circular machines, garment length is programmed courses — so cutting a 7/8 from a full-length block is a program change, not a new pattern. That makes multi-length testing cheap at sample stage: knit the same style at two lengths, fit both, keep the winner. Hem finish matters more than usual at 7/8 (the hem sits in sight); clean knit-in hems beat bulky coverstitched ones there.

What a launch actually needs

Two lengths cover most lines at launch: 7/8 as the hero, biker for summer and sets. Add full length when your size data shows demand at the taller end; add capri only if your audience skews to it — it is the weakest seller of the four in most markets. Each added length is a full size-curve of inventory, the same maths as colorways.

How Yesseam handles lengths

Stock styles list garment inseam per size on every product page, and custom programs can sample one style at two lengths in the same 7–10 day round — the cheapest fit experiment in the catalog.

FAQ

Is 7/8 length shorter than full length?

Yes — by roughly 5–8 cm at the same size. A 7/8 ends above the ankle bone; a full length reaches it. The name refers to covering seven-eighths of the leg, not to sizing.

What inseam should biker shorts be?

The market clusters in three bands: 13 cm (5″) fashion-short, 20 cm (8″) the current default, and 25 cm (10″) modest/training cut. 8″ is the safest single choice for a first drop.

Should petite customers size down for length?

No — sizing down changes width everywhere, not just length. The right answers are a stated garment inseam on the chart so they can choose, or a dedicated shorter-inseam option on hero styles.

Do different lengths need different MOQs?

In seamless, length variants of the same style are knitting-program changes, so they are usually treated as one style for development — though each length still needs its own inventory commitment per colour.

What does 7/8 mean on leggings?

It describes how much of the leg the legging covers, not a size: a 7/8 legging ends above the ankle bone, which at size M is an inseam of roughly 63–66 cm (25–26″) against about 71 cm (28″) for full length. So 7/8 leggings are not full length — they are the same garment cut 5–8 cm shorter, which is why they read as full length on shorter customers and as a cropped length on taller ones.

Which length should tall customers choose?

Full length, and a high rise. A 7/8 cut for an average-height fit model becomes a capri on a customer around 180 cm, and a mid-rise waistband sits low on a long torso. The practical fix is a size chart that states garment inseam in centimetres, so a tall customer can pick by measurement rather than by the word "full".

How long are compression shorts?

They sit in the same 13–25 cm (5–10″) inseam band as biker shorts. Which end of the band suits depends on the activity: shorter cuts for running and studio classes, longer cuts where the complaint is the leg band riding up during squats or lunges.

What are seamless shorts?

Shorts knitted as one tube on a circular machine instead of being cut from fabric and sewn, so there is no inner-thigh seam and usually no side seam either. That removes the two seams that chafe most in training, and lets the waistband, leg band and any compression zones be knitted in rather than sewn on.

What makes seamless shorts good for gym or running?

Three things you can check: a leg band that grips without cutting in (knitted in, not a sewn-on elastic), enough fabric density that the short stays opaque in a deep squat, and an inseam matched to the activity — the longer end of the 13–25 cm band for lifting, the shorter end for running. Most performance seamless shorts are nylon/elastane; cotton-rich versions exist for lounge wear but lose shape at the hem under repeated stretching, which is why they are rare in training styles.

What are 7/8 leggings?

Leggings cut to end just above the ankle bone rather than at it — seven-eighths of the full leg. At size M that is an inseam of roughly 63–66 cm (25–26″), against about 71 cm (28″) for full length. They show a little ankle, sit cleanly over trainers without bunching and wear as a neat full length on shorter customers, which is why many premium lines cut their main legging as a 7/8.
