Size 31 in Women’s Jeans: Is It Actually Small, Medium, or Big? Find Out Now!

When shopping for women’s jeans, sizing can be confusing—especially when it comes to size 31. Is it a true small, a medium, or perhaps a bigger fit? With so many brands defining sizes differently, understanding what size 31 really means can save you time, money, and endless online returns. In this comprehensive guide, we break down everything you need to know about size 31 in women’s jeans to help you make confident fits every time.

What Does Size 31 Actually Mean?

Understanding the Context

Size 31 typically falls within the mid to small size range, but whether it’s small, medium, or big depends primarily on the brand and style. In general, size 31 is closest to a small to medium fit (ideal for bodies in the range 28–34 inches waist circumference), especially in slim or regular-waist jeans. However, some brands market it as a “medium-sized” fit or even offer it in extended lengths and relaxed cuts that may appear larger.

How Does Size 31 Compare Across Common Brand Standards?

  • Levi’s 31: Often considered a small to medium size, matching women’s sizes 30–32 waist. This size offers a sleek, skinny or slim fit with slightly shorter lengths.
  • Wrangler 31: Usually aligns with medium to slightly large, featuring a bit more room in the hips and thighs for a balanced fit.
  • Madewell 31: Frequently branded as a medium size with a relaxed, straight-leg cut for comfort.
  • Target / Amazon Essentials 31: Usually fits snugly as a small to medium, ideal for petite or average builds (28–34”).

Key Measurements to Consider

Key Insights

To determine if size 31 is right for you, compare your measurements with the brand’s sizing chart:

  • Waist circumference: Look for 28–34 inches (71–86 cm) to fit properly.
  • Hip width: If your hips measure 38–44 inches (97–112 cm), size 31 may accommodate movement.
  • Preferred fit style: Slim jeans shrink and feel tighter, while relaxed or tapered styles offer room. Size 31 in loose fits often corresponds to medium or larger.

Size 31: Is It Small, Medium, or Big?

Small (S): Typically fits women with waists under 30 inches; size 31 rarely fits this.
Medium (M): Most accurate general fit—ideal if your waist is 30–34 inches.
Big (L): Usually starts around 34+ waist inches; only larger builds should consider this.

Why Understanding Size 31 Matters

Final Thoughts

Getting the correct fit can transform your jeans experience—flattering silhouettes, better comfort, and durability you’ll love. Misinterpreting size 31 as overly small or overly large leads to disappointment. Instead, always:

  • Check your local brand’s sizing guide.
  • Measure your waist and hips.
  • Try jeans on or review return policies.
  • Consider the cut—skinny, straight, or relaxed affects perceived size.

Final Thoughts

Size 31 in women’s jeans is not universally small or big—it’s best classified as a medium fit for most women, particularly those with a 28–34” waist. However, sizing varies, so take note of brand-specific measurements and personal measurements before purchasing. With this insight, you’ll walk confidently into your next pair of 31 jeans—knowing exactly what expectations to set.
