Flared Yoga Pants Sizing Guide: How to Get the Right Fit | Measure, Don’t Guess

Flared yoga pants fit correctly when the waistband sits flat without digging, the seat and thighs are smooth rather than overstretched, and the hem skims your shoe without dragging.

Most bad flared-yoga-pants fits trace back to one shortcut: buying by height. Torso length, rise, waist, and hip all move independently, so two people the same height can need different sizes and different inseams. The fix is a tape measure and about ten minutes. Measure your waist, hip, and inseam, match those numbers to the exact product’s chart, then pick your length by inseam and confirm with a squat-and-walk test before the tags come off.

What Numbers Do You Actually Need?

Three measurements drive the whole decision: waist at its narrowest point, hip at the widest part of the buttocks, and inseam from groin to ankle bone. Take all three with a flexible tape held level and snug — close to the body but never compressing it.

lululemon’s official procedure is precise about each one. Measure the waist around its smallest point. Measure the hip around the widest part of the buttocks while standing with feet hip-width apart. Measure inseam along the inside of the leg from the groin to the ankle bone. Write all three down; you’ll use them in the next step.

Reading A Size Chart Without Getting Burned

Size comes from the waist-and-hip chart for that specific product, and length comes separately from the inseam. Treating them as one decision is where most sizing errors start.

Here is how lululemon’s women’s pants chart maps out, so you can see how much ground the numbers cover:

Two rules keep the chart honest. First, use the exact product’s current chart — sizes are not consistent between brands, models, or collections, and a regional version of a chart should not be assumed identical to the US one. Second, when your waist and hip point to different sizes, follow the measurement governing the garment’s tightest area, which for close-fitting flare leggings is usually the hip. Then check the manufacturer’s fit notes for that specific cut.

Is A 32-Inch Inseam The Same As “Regular”?

No — and that mix-up causes a lot of returns. Inseam is a product-specific number, and “regular” is a length label that different products define differently.

A regular mini-flare from lululemon carries a 32-inch inseam, intended to skim the floor for people roughly 5 feet 5 inches to 5 feet 8 inches tall. A comparable high-rise flare cut lists Regular at 30½ inches, Petite at 28½, and Tall at 33½. Same brand, same label, different numbers.

Pick length by where you want the hem to land in the shoes you’ll actually wear with the pants. A full-length flare should skim the floor; fabric pooling under your heel means the inseam is too long. The mini-flare’s fit notes describe a high-rise, body-hugging cut from waist to knee with a subtle flare below — a shape that reads best with a clean hem line.

Model stats, including the 5-foot-9 model in size 6 on that product page, are styling context, not sizing advice.

What Should You Check Before Committing?

Wear the pants for a real movement test: squat, sit, bend, and walk. The waistband should stay put without rolling or leaving deep pressure marks, the fabric shouldn’t go sheer when it stretches, and the flare shouldn’t catch under your heel.

A waistband that gaps or digs usually signals the wrong size or rise, not a styling quirk. If everything fits except the length, a tailor can hem the leg — lululemon recommends one capable of reproducing its double-stitching so the original construction survives. For a shortlist of cuts that already pass these checks, this tested roundup of the best flared yoga pants covers real-world fits across body types.
