What Is the Difference Between Petite and XS Sizing?
Share
When it comes to finding the perfect fit, clothing sizes can be downright confusing—especially for petite and extra-small (XS) women. As a professional fashion designer specialising in petite (1.5m-1.59m/ 4'11.1"-5'2.6") and extra-petite (1.4m-1.49m/ 4'7.1"- 4'11") clothing, I’ve seen firsthand how often these two terms are misunderstood. Many people assume that “petite” and “XS” mean the same thing. But in reality, they serve two completely different purposes.
In this article, I’ll break down the difference between petite and XS sizing so you can shop more confidently and find garments that truly fit your frame.
What Does ‘Petite’ Mean in Sizing?
Petite sizing refers to clothing designed specifically for women who are shorter in height, typically 5’4” (163 cm) and under. It has nothing to do with weight or body shape. Petite garments are proportioned differently to fit shorter torsos, arms, legs, and overall frames.
For example:
- Petite Dresses and tops have higher waistlines to align with a shorter torso.
- Sleeves and pants are shorter in length.
- Necklines are often adjusted for smaller upper bodies.
Petite sizing caters to height, ensuring that clothes don’t overwhelm a shorter figure.
What Does XS Mean in Sizing?
XS, or extra small, is a size that indicates a smaller fit in terms of width, not height. It’s part of the standard sizing range (XS, S, M, L, XL) and is designed for women with narrower measurements in the bust, waist, and hips.
Unlike petite sizing, XS clothing is not adjusted for height. An XS top or dress may still have long sleeves or a low waistline that doesn’t align with a petite frame, even if the width fits perfectly.
Key Differences Between Petite and XS Sizing
1. Height vs. Width
- Petite sizing adjusts proportions to fit shorter heights.
- XS sizing focuses only on smaller body widths without accounting for height.
If you’re short but wear XS, you might find that sleeves and pant legs are too long, or that waistlines hit below your natural waist.
2. Proportions
Petite clothing is specifically tailored for smaller proportions.
- Shorter inseams for pants and jeans.
- Higher darts and waistlines in dresses and tops.
- Adjusted armhole placement to prevent fabric bunching around the shoulders.
XS clothing, by contrast, uses standard proportions meant for average-height women, just scaled down in width.
3. Body Shape Considerations
Petite sizing is designed with shorter, more compact body shapes in mind, but XS assumes the wearer has a standard frame. This can lead to fit issues for petite women wearing XS, such as:
- Excess fabric in areas like the shoulders or knees.
- Ill-fitting waistbands that don’t sit where they should.
How to Tell If You’re Petite or XS—or Both
It’s possible to be both petite and an XS size, but not all petite women wear XS, and not all XS women are petite. Here’s how to determine which category you fall into:
You’re Petite If:
- You’re 5’4” (163 cm) or shorter.
- Clothing often feels too long in the sleeves, pants, or torso.
- You find that standard sizes overwhelm your frame, even if the width is correct.
You’re XS If:
- Your bust, waist, and hips fall into the XS measurement range.
- Clothing fits well in width but is often too long.
Common Myths About Petite and XS Sizing
Myth 1: Petite and XS Are Interchangeable.
This is the most common misconception. Petite is about height; XS is about width. While some women are both petite and XS, they are distinct sizing categories.
Myth 2: Petite Sizes Are Just Shortened Standard Sizes.
Petite clothing isn’t simply “shortened.” It’s entirely re-proportioned to fit shorter frames. Waistlines, darts, and hemlines are strategically adjusted.
Myth 3: If You’re Petite, You Can Only Shop in Petite Sections.
While petite sections are ideal, you can still wear standard sizes. The key is knowing how to tailor your garments for the perfect fit.
Why Petite Women Often Struggle With XS Clothing
Many petite women assume that XS will solve their fit problems, but this often leads to frustration. Here are some common issues:
- Sleeves that extend past the wrists.
- Pants with extra fabric pooling at the ankles.
- Dresses with waistlines that sit too low.
Petite sizing eliminates these problems by tailoring garments to fit shorter frames.
How to Shop Smart as a Petite or XS Woman
1. Look for Brands That Cater to Petites
Specialty petite brands like House of Arti (my brand) are dedicated to designing clothes specifically for shorter women.
2. Use Size Guides
Always check the brand’s size chart. Petite and XS sizing can vary between retailers.
3. Invest in Tailoring
If you can’t find the perfect fit, tailoring is worth it—especially for professional or formal wear.
4. Prioritise Petite Proportions for Dresses and Pants
Petite sizing is crucial for garments like dresses, trousers, and jumpsuits, where proportions play a huge role in overall fit.
Answering your Question in Short: What Is the Difference Between Petite and XS Sizing?
The difference between petite and XS sizing lies in their focus: petite sizing is designed for women 5’4” (163 cm) and under, adjusting proportions such as the lengths, like sleeve lengths, inseams, and waistline placement to fit shorter frames. In contrast, XS sizing caters only to body widths such as bust, waist, hips, and thigh circumferences. While petite is about height and proportions, XS focuses solely on body width measurements.
Final Thoughts: Why Understanding the Difference Matters
As a petite woman and fashion designer, I know how life-changing it can be to wear clothes that truly fit. Understanding the difference between petite and XS sizing is the first step to building a wardrobe that flatters your unique frame.
Whether you’re shopping for everyday essentials or elegant statement pieces, knowing what to look for will save you time, money, and countless returns.
Remember: petite and XS are not the same. If you’re short, seek out brands specialising in petite sizing, and don’t be afraid to tailor your XS favourites for a flawless fit.
