Understanding how maternity sizes work can make shopping for maternity clothes much easier—and more fun! While it may be tempting to size up in regular clothes sizing as you experience weight gain, maternity garments are specifically designed to accommodate a growing bump while still fitting comfortably in other areas.

Below, we’ll walk through key factors such as waist size, measuring around the fullest part of your hips, and interpreting size charts—all to help you find your perfect maternity fit.

Start with Your Pre-Pregnancy Size

A good starting point is to choose the numbered sizes (6, 8, 10, etc.) or S, M, L that correspond to your pre pregnancy size. Maternity clothing typically aligns with these traditional clothing sizes, but includes extra fabric and stretch where needed—particularly around the belly.

If you feel you have gained extra weight beyond your bump, it can help to take fresh measurements. You might compare them to a brand size chart, especially if your waist was previously around 28 inches and is now larger.

Measuring the Fullest Part of Your Hips and Waist

When finding the right maternity clothes, it’s essential to measure yourself accurately:

  • Hips: Measure around the fullest part of your hips (usually around 20–23 cm below your natural waist).

  • Waist: For maternity sizing, you often measure above your bump instead of your natural waistline. If a size chart calls for your waist size, be mindful that your baby bump alters where this measurement should be taken.

These measurements will help you determine how a brand’s maternity dresses, jeans, or maternity bras might fit. If you need extra detail, check out the Angel Maternity Size Guide for specific instructions.

Pay Attention to Weight Gain

Pregnancy brings natural weight gain, and every woman carries it differently. That’s why it’s best to track how your body changes rather than focusing on a single clothing label. When you’ve gained extra weight, you may need to adjust your chosen size or look for styles with more stretch.

Different Brands and Their Approaches

Each label may handle maternity sizes work a bit differently—some rely on numbered sizes, while others simplify it to S, M, L, and so on. Looking at each brand size guide can be especially helpful if you’re unsure which option to pick. Remember, if one style feels snug, you can always try the next size up for added comfort.

FAQ

How do you know your size in maternity clothes?

Start with your pre pregnancy size, then measure around the fullest part of your hips and, if needed, above your growing bump. Compare these measurements to a size chart to get the best fit. Every brand’s approach to maternity clothing may vary, so it’s always wise to consult their specific guide.

How many sizes should I size up when pregnant?

Generally, you don’t need to size up when buying maternity clothes. Instead, choose your usual size and rely on maternity-specific features like extra stretch. If you feel you have gained more weight than average during pregnancy, you might consider going up one size—especially in more fitted garments.

Finding the right pregnancy clothing is all about striking a balance between comfort and style. By checking size charts, measuring correctly, and focusing on maternity dresses or separates designed with room for your growing belly, you can confidently pick pieces that make you look and feel fabulous throughout your pregnancy journey.
