How Should Barrel Leg Trousers Fit? Size, Rise and Length

How should barrel leg trousers fit? They should sit neatly at the waist and hip, carry their room through the thigh and knee, and then taper in again towards the ankle, finishing at or just above the ankle bone. That roominess through the leg is the design rather than a sizing mistake, which is why most people are best in their usual size rather than going up.

Once you know where the shape is meant to sit close and where it is meant to be generous, the fit becomes much easier to judge, whether you are trying a pair on or buying online. This guide covers where a barrel leg should sit, which size to take, how the fabric changes the fit, how long they should be, and what to look for if you are petite. For outfits once the fit is right, see our guide to how to style barrel leg trousers.

Where a barrel leg should sit on the body

A barrel leg anchors at two points, the waist and the ankle, with the curve happening in between. The waistband sits at your natural waist, and on most of our styles the rise comes to around the belly button, a comfortable mid rise that suits a tucked top. When the fit is right, you can see the line of your waist and the neat line across the hip, and the volume is all in the leg where it belongs.

On our Billie Barrel Leg Trousers, a seam placed off centre down the front splits the leg roughly two thirds to one third, drawing a vertical line that breaks up the width. If your trousers seem to widen you all the way up rather than sitting neatly at the waist and hip, the waist is usually too big rather than the leg being too wide.

What size should you take in barrel leg trousers?

Take your normal size. The volume is built into the leg, so there is no need to size up for the relaxed shape, and sizing up tends to leave the waist gaping when you sit down. If you are between sizes in the cotton Billie trousers, Hayley usually suggests the smaller of the two, since the waist is the part that needs to fit. She is 5 foot 8 and a size 8 to 10, and wears a 10.

The jeans are a little different. Denim can sit very slightly snugger than the cotton twill, so if you are between sizes in the jeans, some customers prefer the larger of their two sizes. If your waist is smaller than your hips, a stretch style will fit more kindly than sizing up in a rigid one. If you do go up in a pair without stretch, a belt will hold the shape at the waist.

The size guide sits on every product page, and the reviews are often the most useful check, because customers tend to note their height and the size they took. Comparing the measurements with a pair of trousers you already love is the other quick test.

How fabric changes the fit

Fabric makes a real difference to how a barrel leg feels and behaves, so it is worth checking the label and thinking about how you want to wear them. The Billie Barrel Leg Trousers and Billie Barrel Leg Jeans are 100% cotton, which holds its shape and keeps the clean, sculptural line the barrel needs. Cotton can feel a little firm at first, so it is worth bending, sitting and moving in a new pair. It softens and gives a little with wear, so there is no need to size up for the first few wears.

The fabric also varies a little from colour to colour, so the size guide on each colour is the best check. The Billie Barrel Leg Striped Trousers are in a slightly lighter fabric than the classic Billies, which suits them to the warmer months and into early autumn.

The Billie Barrel Leg Faux Leather Trousers fit differently from the cotton pairs. They have a fully elasticated waist, which the cotton Billies do not, and they come up slightly bigger, so if you are between sizes, the smaller size is the one to choose. They are also cut shorter, to the same length as the other Billies when rolled, and they are not designed to roll, because the lining would show.

If you want more give, the Emmie Barrel Leg Jeans are the softer take on the shape, a subtler, slightly narrower barrel with a touch of elastane for stretch and recovery. They are true to size, so again take your usual size. Stretch is the better choice if you sit for long stretches or want a fit that follows your curves, and good recovery means it springs back into shape rather than bagging at the knee.

How long should barrel leg trousers be?

Barrel leg trousers and jeans look best finishing at or just above the ankle bone, so that a little ankle shows between the hem and your shoe. That is why the cotton and denim Billies arrive with the hem rolled. You can keep the roll to show the ankle, or let it down to wear them full length.

Both lengths work, so this comes down to your height and how you like to wear them. One of our models is 5 foot 11 and wears the Billie full length, while Hayley rolls hers to finish just above the ankle. A rolled hem with a little ankle on show feels relaxed and current, because it breaks up the proportions in the same way a glimpse of wrist or collarbone does. Full length feels slightly more formal, especially in a neutral such as ecru.

For a neater cut that sits on the ankle without a roll, the Eadie Pleat Front Trousers are a subtle, tailored barrel leg, somewhere between a barrel and a straight leg.

Barrel leg trousers if you are petite

Barrel legs are not only for tall women, and customers from 5 foot 1 to around six foot wear the Billie. On a shorter frame, the fit to look for is a neat one around the hip, so the shape does not add width there, and the length to aim for is just above the ankle. Rolling the hem is the easiest way to get it, and if you would rather wear them full length without a roll, the hem can be taken up.

A top tucked in to show the waist and a narrower shoe with a slight point both help a shorter frame, because they keep the line long from the waist to the toe. The Eadie, with its flat pleats and neater leg, also works well on petite frames.

Three quick fit checks before you decide

If you only do three things, do these. First, sit down, because the waist should stay put without gaping at the back, which is the clearest sign you have the right size. Second, bend and move, particularly in structured cotton, so you know you have room through the thigh and seat. Third, look at the line in a mirror from the side as well as the front, and check the trousers sit neatly at the waist and hip with the volume in the leg.

Frequently asked questions

Should barrel leg trousers be tight or loose?

Neither, really. They should sit close and neat at the waist and hip, then be loose and roomy through the leg, so if the waist feels loose, the trousers are probably too big.

Do you size up or down in barrel leg trousers?

Take your usual size, since the room is designed into the leg and going up tends to leave the waist gaping. If you are between sizes in the cotton trousers or the faux leather, take the smaller size, and in the denim some customers prefer the larger.

How long should barrel leg jeans be?

Barrel leg jeans look best finishing at or just above the ankle bone, with a little ankle on show. A rolled hem is the easiest way to get that length, while full length reads slightly more formal on taller frames.

Where should barrel leg jeans sit?

They should sit at your natural waist, with the rise coming to around the belly button, and fit neatly across the hip. The volume starts below the hip, and the hem should finish at or just above the ankle.

Can you roll faux leather barrel leg trousers?

The faux leather Billies are not designed to roll, because the lining would show. They are cut shorter instead, to the same length as the other Billies when rolled, so they finish just above the ankle as they are.

What is the difference between the Billie and Emmie fit?

The Billie Barrel Leg Trousers and Jeans are structured 100% cotton that holds a clean, confident shape. The Emmie Barrel Leg Jeans are a softer, slightly narrower barrel with a touch of elastane for stretch and recovery, and both are true to your usual size.
