Choosing a bathing suit for US Size 14 starts with taking four exact body measurements and matching them to the specific brand’s size chart, because sizing varies significantly between labels and suit styles.
One wrong assumption—like picking a suit based on your jean size—can send you back to the cart within minutes. Size 14 in US swimwear typically means XL, but what XL means shifts between a leisure suit from Madewell and a racing suit from Speedo. The fix is simple: measure the right spots, compare against the chart for that exact suit, and know which rules to break and which to follow. Here is how to nail the fit on the first try.
The Four Measurements That Determine Size 14 Fit
Every swimsuit size chart is built on the same four core numbers. Measure in your underwear with a soft tape, keeping it snug but not tight. Write each number down as you go.
- Bust: Measure around the fullest part of your chest, tape parallel to the floor. For Size 14, look for 41–42 inches (104–107 cm) on the chart.
- Waist: Measure at your natural waist—the narrowest point, usually near the belly button. The Size 14 range is typically 35–36 inches (89–91 cm), though some brands like Madewell list 33 inches for this size.
- Hips: Measure around the widest part, before the thigh narrows. Expect 44–46 inches (112–117 cm) for Size 14, though Madewell’s chart shows 43 inches.
- If you skip this measurement on a one-piece, you risk the dreaded “wedgie” or a looser suit.

The One Rule That Overrides Everything Else
Ignore your pant size entirely. Bust measurement is the primary driver for tops and one-pieces, not the number on your jeans. A woman who wears Size 14 in pants may need a Size 16 or a Size 12 in a swim top depending on her bust-to-hip ratio. The brand’s specific size chart is the only authority—never assume universal sizing across labels. Madewell’s Size 14/XL lists a 33-inch waist and 43-inch hips, while the standard chart shows 35–36 and 44–46; both are correct for their own suits. Check the chart every time.
If your measurements fall between two sizes, pick the smaller size for swimwear—fabric stretches when wet, and a snug suit reduces water drag and chafing. The exception: if the smaller size causes red marks or restricts breathing, go up a size. Comfort under tension matters more than the label.
Brand Variations and Style Tips
Speedo and TYR target competitive swimmers with compression fits; their Size 14 fits tighter than a leisure brand like Madewell. For racing suits, size up if you want normal comfort. For leisure suits, size down if you are between sizes, but avoid pre-defined cups if your bust measurement falls outside the chart’s range—adjustable or tie-back styles give you more wiggle room.
| Brand / Style | Size 14 Fit Approach | Key Tip |
|---|---|---|
| Standard Leisure Suit | True to chart (bust 41–42″, waist 35–36″) | Take torso measurement for one-pieces |
| Madewell Suits | Chart shows 41″ bust, 33″ waist, 43″ hips | Cross-check waist and hip against your own—likely runs slimmer at waist |
| Speedo Racing Suits | Tighter compression fit; size up for comfort | Match waist size (measure 1 inch above natural waist) |
| TYR Racing Suits | Similar compression; tighter than leisure | Sizing up one full size is common for lap swimming |
| One-Piece Suits | Circular torso 68″ is the make-or-break number | If torso is longer than chart, look for “long torso” options |
When in doubt, order two sizes and return the unused one through a retailer with an easy return policy. Swim fabric stretches when wet; a suit that feels “perfect” dry may bag out as soon as you hit the water, so trust the snug fit.
FAQs
Can I wear a Size 14 in bikini tops if my bust is 44 inches?
Not unless the brand’s chart specifically covers that measurement. Most Size 14/XL tops cap the bust at 42 inches. If yours runs larger, look for brands that sell tops by cup size or choose an adjustable triangle style that allows more coverage.
How tight should a one-piece swimsuit feel when dry?
Snug enough to lie flat against the body without wrinkles or gaping, but never painful. You should be able to breathe deeply and move your arms freely. If the suit leaves red marks after a five-minute try-on, it is too tight.
Is a Size 14 swimsuit the same in Australia or the UK?
No. A US Size 14 (XL) roughly corresponds to an Australian Size 18W and a UK Size 18. Always check the region-specific chart on the retailer’s site—international sizing drifts by up to two full sizes in some cases.
