Levi's Fit Numbers Explained: 501, 511, 512, and More

How Levi's numbers work

Each number in Levi's name is not a size, it is a fit code. The code stands for a specific combination of rise, thigh width, knee width, and leg opening. Two pairs in the same waist size can feel completely different if they carry different numbers. That is why you see 501, 511, and 512 side by side in stores: same brand, different silhouettes.

To decode a fit number, you need to separate three zones: the rise (from crotch to waistband), the thigh (around the upper leg), and the taper (how much the leg narrows from knee to ankle). Some numbers prioritize a roomy thigh with a straight leg, while others hug the body from waist to cuff. You can learn more about these measurements in our jeans fit types comparison guide.

The classic straight: 501 and 505

The 501 is the original button-fly straight leg. It sits at the natural waist, gives the thigh a relaxed fit, and falls straight from the knee to the hem. It is the safest starting point if you are unsure about your cut. The 505 is a similar straight leg but with a zip fly instead of buttons, and it usually sits slightly lower on the hip.

Both work for most body types because they do not force the leg into a taper. They look good with boots, sneakers, or dress shoes. If you want a no-nonsense, timeless shape, start with a 501. If you prefer a zipper and a slightly more modern waist, try the 505. For top picks, see our best Levi's jeans guide and our men's straight leg jeans roundup.

Slim and tapered: 511 and 512

The 511 is a slim straight with a tapered leg opening. It fits closer through the thigh than the 501 but still leaves enough room for movement. The taper from the knee to the ankle gives a clean, modern line that works with low-profile sneakers or boots. It is one of the most popular numbering codes for men who want a fitted look without going skin-tight.

The 512 goes a step further. It is a true slim taper: thigh is snug, knee is narrow, and the leg opening is much smaller than the 511. It is designed for a sleek, almost skinny appearance, but it is not as tight as a skinny jean. If you have athletic thighs, the 512 might feel restrictive; if you have average or slim legs, it will follow your silhouette closely.

Roomier cuts: 541 and 550

Not every build wants a slim fit. The 541 is labeled an athletic fit: it gives extra room in the thigh and seat, then tapers down the leg. This is ideal if you have strong legs from cycling, lifting, or any activity that fills out the upper leg. The taper keeps the ankle from looking baggy, so you get comfort and a modern silhouette.

The 550 is a relaxed straight. It sits at the mid waist and runs loose from hip to hem, with no taper. It is a classic workwear shape that feels roomy in the seat and thigh. If you prefer loose comfort or need extra space for work or outdoor activities, the 550 is a reliable choice.

Women's numbered fits

Levi's also uses numbers for women's fits, though the lineup differs from men's. The women's 501 offers a high-rise straight leg with a slightly relaxed thigh. The 721 is a high-rise skinny, and the 311 is a mid-rise skin-tight skinny. These numbers follow the same logic: rise, thigh, and taper, but with proportions shaped for the female body.

When ordering online, pay attention to the fit name next to the number. A 'high-rise skinny' and a 'mid-rise straight' will fit very differently. For women's picks, see our best women's jeans guide and our best women's high waisted jeans guide.

Match the fit to your body

The easiest way to choose a number is to think about your thigh circumference and your preferred leg opening. Measure the fullest part of your thigh and compare it to the listed thigh measurement for each fit (if you have a real pair, take the measurement on the jeans). If your thigh measurement falls between sizes, go for the fit with more room in that area.

Next, decide how much taper you want. A wider taper (501, 550) gives a straight column look; a moderate taper (511, 541) narrows slightly; a strong taper (512, 721) hugs the calf. The leg opening should balance with your footwear: a narrow opening sits nicely over slim shoes, while a wider opening clears boots.

Rise matters too. A mid rise (around the belly button) is flattering for most. A high rise sits above the belly button and can lengthen the leg. A low rise sits below the navel and is more casual. Our rise measuring guide will help you understand where each sit.

Ordering online: what to check

Before you click add to cart, open the size chart and look at three numbers: the rise, the thigh, and the leg opening. They are usually listed in inches or centimeters. Compare them to a pair of jeans you already own and like. If the brand does not list measurements, search for the fit number in our guides and read what other buyers mention about the cut.

Remember that wash and fabric composition can change the fit. A stiff rigid denim will not stretch much, while a stretch blend with elastane can give a little. If you are between sizes, consider that stretch will accommodate some movement, but rigid denim will not. Read our stretch denim vs rigid article and our non-stretch jean size guide to make the right call.

What to pick for your needs

Questions

What does the number on Levi's jeans mean?

The number is a fit code, not a size. It indicates the cut of the jean: the rise, thigh width, and leg taper. For example, 501 is a classic straight, 511 is a slim taper, and 512 is a tighter taper.

Which Levi's fit is the most forgiving for large thighs?

The 541 athletic fit is designed with extra room in the thigh and seat before tapering down. The 550 is also roomy and straight. Avoid 512 or other skinny fits if you want comfort in that area.

What's the difference between the 501 and the 505?

Both are straight leg cuts, but the 501 uses a button fly and sits at the natural waist. The 505 uses a zip fly and often has a slightly lower rise. Most wearers will find them similar in overall silhouette.

Is the 511 a skinny jean?

No, the 511 is a slim straight with a modest taper. It fits closer than a uniform straight but is not as tight as the 512 or a skinny fit. The 512 is the true skinny taper.

Do Levi's numbers stay the same for women?

No, women's fits use different numbers. The women's 501 is a high-rise straight, the 721 is high-rise skinny, and the 311 is a mid-rise skinny. Always check the description next to the number for the rise and silhouette.
