Levi’s jeans numbers denote the fit, rise, leg shape, and fly; extra digits and letters mark the wash, size (W/L), and production details.
Open a Levi’s tag and you’ll see a three-digit model like 501 or 511, a style code such as 00501-0115, and a size like W32 L32. Those codes map to fit, finish, and sizing. If you’ve ever wondered “what do the numbers mean on levi’s jeans?”, you’re in the right place.
Levi’s Number System In Plain Words
Levi’s assigns a three-digit “fit number” to each core jean. That number locks in the rise, leg shape, and fly style. The brand describes these numbers as a shorthand for fit details like rise, fly, and leg opening, with classics like 501 and modern slims like 511 following the same logic across collections . You can see that explanation in Levi’s answers to common questions, which spell out what the numbers stand for.
Common Levi’s Fit Numbers And What They Mean
Here’s a quick comparison of popular men’s fits.
| Fit Number | Core Shape & Specs | Best For |
|---|---|---|
| 501 | Original straight; sits at waist; button fly; regular through thigh | All-purpose straight denim with heritage styling |
| 505 | Straight leg; typically zip fly; mid rise; a late-’60s classic revived from the archives | Straight-leg fans who prefer a zipper instead of buttons |
| 510 | Skinny through seat and leg; narrow opening (brand skinny baseline) | Streamlined, tight silhouette |
| 511 | Slim from hip to ankle; narrower opening than straight; zip fly; more tailored than 514 | Slim look without going skinny |
| 512 | Slim taper; room in thigh with taper to ankle (modern slim-taper profile) | Slim top with a sharper ankle line |
| 514 | Straight fit; eased compared with 511; zip fly; “sweet spot” straight profile | Straight comfort that isn’t baggy |
| 517 | Boot cut; straight through thigh with a boot-friendly opening | Wearing boots or western footwear |
| 541 | Athletic taper; extra room in seat/thigh with a taper to the hem | Muscular legs, bigger seat and thighs |
| 550/559 | Relaxed or relaxed straight; more ease through seat and thigh | Laid-back fits with extra space |
| 569 | Loose straight; roomiest in the 500s range | Baggy comfort and straight hems |
What Do The Numbers Mean On Levi’s Jeans? (Deep Dive)
The headline number (501, 505, 511, and so on) is the fit family. That number anchors the rise, leg pattern, and fly type across colors and fabrics. A 511 Slim will keep the same overall proportions whether you buy black, stone, or selvedge denim. The brand’s guides call out these fit names side-by-side so you can compare leg openings and rises before you add to cart .
Next comes the longer “style number” you’ll see on product pages and carton labels. It often looks like five digits, a hyphen, and four more digits (example: 00501-0115). The left block covers department and fit family; the right block is the finish code for that SKU. On the 501 Original, the 0115 finish appears with rinse/dark wash listings on Levi’s regional sites, while the underlying 501 shape stays the same straight fit .
How To Read Size Numbers (W/L) Correctly
Levi’s prints sizes as waist by inseam (W/L). A tag showing W32 L32 means a 32-inch waist and a 32-inch inseam. For step-by-step measuring help, Levi’s size guide shows where to place the tape and how to match your numbers to the tag . Women’s size charts are organized by body measurements as well, so the same W/L logic and measuring tips apply across the range .
Wash, Finish, And Fabric Notes That Appear As Numbers
The extra digits after the fit number tell you which finish you’re getting. Make this practical: imagine you tried a 511 Slim in store and loved the fit. You can later match the exact wash online by checking the finish code on the hang tag and searching for that same code. On official product pages you’ll see the full style number under “Style #,” which pairs the fit family with the finish code for that SKU .
Some codes also hint at fabric behavior. Classic 501 Shrink-to-Fit denim, for instance, arrives un-sanforized, so you buy up to allow for shrinkage; Levi’s sells it under the same 501 family but labeled Shrink-to-Fit to make that clear on the page . Standard 501 Original in rinse or stonewash is pre-shrunk and keeps its tagged size once washed and worn .
One H2 With A Close Variant: Decoding Levi’s Numbers For Fit Choice
If you’re choosing between close Levi’s numbers, line them up by rise, leg, and thigh room. Slim numbers like 511 and 512 share a trim seat; the 512 tapers harder at the ankle, while 511 stays narrow but straighter through the leg . Straight numbers like 501 and 514 keep a classic line; 514 adds ease, while 501 keeps the button fly heritage and a regular thigh . Athletic cuts like 541 use a roomier top block with a clean taper, so bigger quads don’t fight the thigh; the leg still narrows to a sharp opening .
Women’s Numbers Work The Same Idea
Women’s Levi’s follow the same three-digit logic by fit family (for instance, 721 High-Rise Skinny or 724 High-Rise Straight). The number points you to rise and leg shape, while the style code ties to the wash and fabric. The size chart pages show how to measure waist and hip .
Historical Marks You Might See On Vintage 501s
On older pairs you may notice extra letters next to the number. Early Levi’s used “XX” to flag extra-strong denim; company catalogs show entries like “XX 501” in the early 1900s, and the XX mark became part of Levi’s lore . Collectors use patch stamps, care tags, and red tab details to date pairs. Levi’s heritage posts note checks like Big “E” vs small “e,” care labels, and inseam stitching style .
Where To Find The Numbers On Your Jeans
You’ll typically find the three-digit fit on the back patch, inside the waistband, and on hang tags. On newer pairs, the full style number often sits near the care label or the small white size tag inside the waistband, while the leather patch still carries the fit family for quick ID . Size appears as W/L on the small white size tag and on the hang tag. Vintage pairs may have the lot number stamped on the leather patch and a different style of internal ticket.
Quick Steps To Choose By Number
Use this checklist whenever you ask, “what do the numbers mean on levi’s jeans?”
Step 1: Pick A Rise And Leg Shape
Pick your rise (at waist, mid, or low) and leg (straight, slim, skinny, tapered, boot). Fit charts show where each number sits and the leg opening .
Step 2: Lock In Your Fit Number
Match the shape to the family: 501 or 514 for straight, 511 for slim, 512 for slim taper, 510 for skinny, 541 for athletic taper. If you wear boots, 517 boot cut keeps the opening wide.
Step 3: Choose The Exact Finish
Scan the “Style #” and note the last four digits; that’s the finish code for the listing. Match those digits to find the same wash online .
Step 4: Confirm Your W/L
Measure waist and inseam as Levi’s suggests, then match to the tag. If you’re buying Shrink-to-Fit, plan for shrinkage; for pre-shrunk 501 or any stretch blend, buy true to size .

Answers To The Most Common Fit Questions
Is 501 The Same As 501 Shrink-To-Fit?
Both sit in the 501 family, so the shape is the same straight pattern, but Shrink-to-Fit ships raw and will tighten after soak and wear. The product page labels Shrink-to-Fit clearly so you can tell it apart from the pre-shrunk 501 Original .
Does 511 Fit Like 514?
No. 511 is slim with a narrower leg; 514 is a straighter, easier cut. Levi’s blogs show them side by side so you can see the opening difference and choose based on how trim you want the lower leg to look .
What Makes 541 Different From 511 And 512?
Room in the seat and thigh. 541 is built for bigger quads and glutes and then tapers cleanly to the ankle, which keeps the outline neat with sneakers or boots .
