If you’re deciding between the Levi’s 505 and the Levi’s 513, the choice comes down to mechanics rather than style trends. Both are straight-leg jeans, but their behavior when worn is very different.
The 505 is a true straightaway with a more massive top block and more traditional bulges. The 513 is a slim straightaway with a trimmer seat and a narrower line through the thigh and leg.
The person prefers comfort and structure. The second prefers a clean outline. If someone has never worked for you, this description will explain why.
short version
Levi’s 505 fits snugly at the waist, seat and thigh and keeps a straight line from knee to hem. Levi’s 513 sits close to the body at the top and tapers slightly through the leg without tapering.
Nobody is better.
They are built for different bodies and different use cases.

Where the Fit Really Lives: Top Block
When jeans look wrong, it almost always starts above the knee. The top block includes the waist, obliques, seat and upper thighs. This is a non-negotiable part of the fit.
The 505 has a more forgiving top block. The camber is mid to mid-high, the seat has more depth, and the thigh offers more clearance. That’s why the 505 has long been favored by men with larger thighs, fuller seats, or anyone who wants a jean that won’t compete with them when sitting, walking, or bending over.
513 strengthens things. The rise is still moderate, but the seat is thinner and the thigh is more controlled. On the right body, it feels clean and safe. On the wrong body, the waist may feel restrictive even if it technically fits.
If you notice strain in the pockets, tension lines under the fly, or pressure through the upper thigh, the issue is the cut, not your size. Downsizing to fix this creates more problems, not less.
Foot size: where priority comes in
Once the top block is fitted, foot size becomes a personal choice.
The 505 runs straight from the knee to the hem. There is no taper and no contraction. This gives the jean visual weight and balance, especially with boots, thick sneakers, or heavy outerwear. This creates an even greater break at the hem.
The 513 is narrower to slightly below the knee. It’s not thin, but it’s not true straight either. That subtle reduction changes how the jean fits and how it reads with narrow shoes. On smaller frames, this can help the leg look neater. On larger frames, this may feel limiting.
The difference is that two jeans that look similar on the hanger look very different in real life.
Fabric, weight and stretch in the real world
Levi’s uses a wide range of fabrics in both models. The pattern remains the same, but not the denim.
505 often appears in heavier, more rigid fabrics, especially in classic washes. These break down slowly and retain their shape over time. Stretch versions exist, but they are less common.
The 513 is often offered in stretch denim. This makes day-to-day living with a slimmer top block easier. This also means that the jeans may seem softer out of the box but may become more comfortable with wear.
Neither approach is better. If you value structure and durability, the 505 usually provides this more consistently. If you want flexibility and ease, 513 often seems more suited.
How do they deteriorate over time
The 505 slowly comes back into shape. The fabric becomes softer, but the silhouette remains consistent. Because there is more room at the top, small variations in denim are less noticeable. This makes it forgiving to wear for months and years.
513 Show changes quickly. Stretched clothes get relief. Thinner cuts reveal the movement of the fabric more clearly. This isn’t a flaw, but it does mean that fit precision matters more from the start.
If you rotate your jeans frequently and care about a clean outline, the 513 works well. If you wear the same pair consistently and repeatedly, the lifespan of the 505 is expected to be longer than expected.
The physical kind of guidance that really helps
For larger thighs or fuller seats, the 505 is usually a safe choice. Bulge and thigh room reduce tension and improve comfort without appearing oversized.
For thin to average builds, the 513 often looks sharper. The narrow seat and legs minimize excess fabric without getting into the skinny area.
For shorter men, the narrower foot of the 513 can create a cleaner line, especially in darker washes. For taller men, the 505’s straight profile helps balance proportions.
It’s important to note that these are not rules, but rather things to consider when considering your options.
How each fit looks in a dress
505 Leans Traditional. It pairs easily with boots, heavy knits and structured jackets. In a darker wash, it still works for a casual office setting.
513 modern bends. It works well with trainers, light layers and clean silhouettes. It often looks more attractive with minimal outfits.
Here the choice of wash matters. A deep, even wash minimizes the visual difference between the two. A faded or stone-washed finish accentuates their differences.
Value, worth and what really matters
The price between 505 and 513 is usually the same. The decision should be based on fit and wear, not cost.
A jeans that fit properly is always better than a cheap option that doesn’t fit properly. Comfort, movement and how the fabric behaves over time matter more than the number on the tag.
Decision
If you want a really straight leg, seat and thigh with more room and a consistently snug fit over time, choose Levi’s 505.
If you want a slim silhouette, a close-fitting top and a straight leg that feels more modern without being tight then choose Levi’s 513.
Measure your natural waist, prefer a clean top block, and let leg shape be the final decision. This approach works far better than chasing trends or size-up tricks.
