Juniors sizing is a clothing fit system commonly used for teen and young-adult styles. On Walmart, you’ll see juniors items labeled with letters (XS–XL) or numeric ranges (for example, 0–21). Because each brand designs and fits a little differently, sizes can vary from item to item.

• Open the size chart on the product page and compare your measurements.
• Check any fit notes (slim, relaxed, cropped, high-rise, etc.).
• Review customer feedback for sizing insights.
• Consider fabric and stretch if noted in the description.

If you’re between sizes, your preferred fit and the garment’s fabric can help you decide.

Youth and juniors use different size systems, so a youth 10–12 doesn’t directly match a juniors size. Youth 10–12 is a kids’ size, while juniors sizing is designed for teen/young-adult styles and listed as letters (XS–XL) or numbers (such as 0–21).

1. Measure bust/chest, waist, hips, and inseam with a soft tape.
2. Open the size chart on the product page (youth or juniors) and compare your numbers.
3. Check fit notes and fabric details to gauge how a garment may wear.

Because brands vary, using the specific item’s size chart is the most reliable approach.

“M” (medium) in juniors indicates a mid-range size within that brand’s juniors run, but the exact measurements can differ by item. Many Walmart product pages show a numeric range or measurement table alongside the letter size.

• Open the item’s size chart and look for the measurements listed for M.
• Compare your bust, waist, hips, and (for bottoms) inseam to that row.
• Check fit notes (slim/relaxed/stretch) to match your preference.
• Scan reviews for comments about running small or large.

Using the specific chart for the exact item is the most dependable way to pick M confidently.

There isn’t a universal conversion because brands and cuts vary. Instead of relying on letters or numbers, it’s best to match your measurements to each chart.

1. Take current measurements (bust, waist, hips, inseam).
2. Open the juniors item’s size chart and find your closest match.
3. Open the women’s chart for a similar item and compare the same measurements.
4. Factor in fit notes (rise, length, stretch, relaxed vs. fitted).

If you’re between sizes, consider fabric stretch and your preferred fit. For peace of mind, check the item’s return policy shown on the product page.

Measuring first can make picking a juniors size easier across different brands.

1. Bust: Measure around the fullest part, keeping the tape level.
2. Waist: Measure at your natural waist (above the belly button).
3. Hips: Measure around the fullest part of your hips/seat.
4. Inseam (bottoms): Measure from crotch to ankle where you want the hem to fall.

• Measure over undergarments for consistency.
• Record your numbers and compare them to the size chart on each product page.
• Review fit notes (slim, relaxed, cropped) to match how you like things to fit.
