This comparison is really about jeans. Levi's is a denim house that sizes by actual waist measurement — a 28 is meant for a 29.25" waist, a men's W32 for a 32.5–33" body waist — while Zara sizes denim on its general EU scale (34–44), where the number is an abstract size, not a measurement. Two completely different systems, so the tables below align rows by body waist, not by label.
One honesty note up front: tops aren't an apples-to-apples comparison here. Levi's is built around jeans, jackets, and tees with its own simple alpha chart, while Zara is a full fashion brand with multiple fit lines. We include a tops table for reference, but the conversion that matters — and the one shoppers actually search for — is the denim one.
The short answer
Different systems, not a fair fight — Zara runs small, while Levi's labels are honest waist inches that vary by fit
On paper Levi's is the more trustworthy label: the size number is a real waist measurement, and men's jeans actually fit about half an inch to an inch of body waist above the number. Zara's denim, by contrast, runs small enough that one size up is standard advice — its EU number tells you nothing about inches, and its garment-to-garment consistency is loose.
But "true to size" at Levi's comes with fit-level asterisks: the Ribcage and Wedgie run small and don't stretch out (size up one, sometimes two), rigid 501s are tight in the hip, and the 511 is snug in the thigh. So the practical rule is: at Zara, distrust the size; at Levi's, trust the size but research the fit. The mapping table below gets you from one system to the other via your actual waist.
Zara vs Levi's at a glance
| Zara | Levi's | |
|---|---|---|
| Denim sizing system | EU numeric (34–44) — the number is an abstract size | Waist in inches; men's sold as W×L (waist × inseam) |
| Overall fit | Runs small — size up in jeans as standard advice | True to size on paper; varies by fit (Ribcage and Wedgie run small) |
| Label honesty | EU number doesn't state a measurement | Label is a real waist measurement; men's fit ~0.5–1" above it |
| Consistency | Loose — varies by line and garment; per-product size tool | Consistent within a fit; the fits themselves differ a lot |
| Stretch and shrink | Stretch varies by style; no shrink-to-fit equivalent | Rigid denim needs a size up; raw Shrink-to-Fit 501s shrink substantially |
Women's jeans: Zara EU size to Levi's size
Rows are aligned by body waist measurement, not by label — Zara uses EU sizes, Levi's uses waist inches. Zara figures are as commonly republished from its per-product size tool; Levi's figures are from its published US guide.
| Zara size | Zara waist | Closest Levi's size | Levi's waist |
|---|---|---|---|
| XS (EU 34) | 62–64 cm · 24.5–25" | 24 | 25.25" · 64 cm |
| S (EU 36) | 66 cm · 26" | 25 | 26.25" · 66.5 cm |
| M (EU 38) | 70 cm · 27.6" | 26–27 | 27.25–28.25" · 69–72 cm |
| L (EU 40) | 74–76 cm · 29.1–30" | 28–29 | 29.25–30.25" · 74.5–77 cm |
| XL (EU 42) | 78–82 cm · 30.7–32.3" | 30–31 | 31.25–32.75" · 79.5–83 cm |
| XXL (EU 44) | 82–88 cm · 32.3–34.6" | 31–32 | 32.75–34.25" · 83–87 cm |
Women's waist and hip at the matched sizes
The two brands build for different proportions: at a similar waist, Zara's chart assumes roughly two inches more hip than Levi's — worth knowing if Levi's fits you in the waist but pulls at the hip, or Zara gaps at the waist.
| Levi's size · waist · hip | Zara size · waist · hip |
|---|---|
| 26 · 27.25" · 69 cm · hip 36" · 91.5 cm | M (EU 38) · 70 cm · 27.6" · hip 98 cm · 38.6" |
| 28 · 29.25" · 74.5 cm · hip 38" · 96.5 cm | L (EU 40) · 74–76 cm · 29.1–30" · hip 102–104 cm · 40.2–41" |
| 30 · 31.25" · 79.5 cm · hip 40" · 101.5 cm | XL (EU 42) · 78–82 cm · 30.7–32.3" · hip 106–110 cm · 41.7–43.3" |
| 32 · 34.25" · 87 cm · hip 43" · 109 cm | XXL (EU 44) · 82–88 cm · 32.3–34.6" · hip 110–116 cm · 43.3–45.7" |
Women's tops for reference (not apples-to-apples)
Body bust/chest measurements aligned by measurement. Treat this loosely: Levi's tops follow one simple chart, while Zara's tops fit differently by line — TRF runs slimmer than Zara Woman.
| Levi's size · chest | Closest Zara size · bust |
|---|---|
| XS · 33" · 84 cm | XS–S (EU 34–36) · 82–86 cm · 32.3–33.9" |
| S · 35" · 89 cm | S–M (EU 36–38) · 86–90 cm · 33.9–35.4" |
| M · 37" · 94 cm | L (EU 40) · 94–96 cm · 37–37.8" |
| L · 39.5" · 100.5 cm | XL (EU 42) · 98–102 cm · 38.6–40.2" |
| XL · 42.5" · 108 cm | XXL (EU 44) · 102–108 cm · 40.2–42.5" |
Switching between Zara and Levi's
- Converting Zara → Levi's: measure your actual waist in inches and buy that Levi's number — don't translate the EU size arithmetically, because Zara's number isn't a measurement.
- At Levi's, pick the fit before the size: Ribcage and Wedgie need a size up (Ribcage sometimes two), rigid 501s are tight in the hip, and the 511 is snug in the thigh on muscular builds.
- At Zara, size up in jeans as the default — and use its per-product size tool, because denim consistency varies garment to garment.
- In tops, a Levi's M is closer to a Zara L than a Zara M — Levi's M fits a 37" (94 cm) chest, which is Zara's EU 40 territory.
Measurements are based on each brand's published size charts and may vary by garment, fabric, and region. For the full charts and fit notes, see the Zara size guide and the Levi's size guide.
Zara vs Levi's sizing FAQs
What Levi's size am I if I wear a Zara 38 in jeans?
A Zara 38 fits roughly a 70 cm (27.6") waist, which lands between a Levi's 26 (27.25") and 27 (28.25"). If you usually size up at Zara because its denim runs small, your true body waist is the better guide — measure it and buy that Levi's number.
Which runs smaller, Zara or Levi's?
Zara, in the sense that matters: its denim runs small against its own chart, so one size up is standard advice. Levi's runs true to size on paper — the label is a real waist measurement — but specific fits like the Ribcage and Wedgie run small, and rigid denim has no give.
What do W and L mean on Levi's jeans?
Waist and inseam length, both in inches — a 32×34 has a 32-inch waist and a 34-inch inseam. Zara has no equivalent: its jeans carry one EU number for the whole garment, with length baked into the style rather than chosen separately.
Can I compare Zara and Levi's tops sizes?
Only loosely. Levi's uses one simple alpha chart (its M fits a 37" chest), while Zara's tops vary by line. By the numbers a Levi's M maps to a Zara L (EU 40), but Zara's TRF pieces run slimmer than that mapping suggests — for tops, treat the two brands as separate sizing exercises.
Do I need to size up in rigid Levi's like I do at Zara?
Often yes, but for a different reason. Zara's size-up rule covers a cut that runs small; Levi's rigid denim is sized honestly but has zero stretch — rigid women's 501s are tight in the hip and usually need one size up, and raw Shrink-to-Fit 501s need extra room for shrinkage. Stretchy Levi's washes can be taken true to size.
