Aqualung Women's Wetsuit Size Chart: Which Fit Guide Should You Use?

By Ethan Brooks

Updated November 2026

The aqualung women’s wetsuit size chart is the starting point for most women shopping for a wetsuit from this brand, but a chart alone rarely settles the question. Two common approaches compete here: following the brand’s published chart using bust, waist and hip measurements, or working from your usual size in another brand and adjusting. The chart-first approach wins for most readers, while the brand-switch approach suits women who already know how a specific cut fits their body.

Criteria	Measure-first (brand chart)	Size-up from your usual size
Starting point	Bust, waist and hip measurements	Your size in other women’s wetsuits
Accuracy for new buyers	Higher	Lower
Best for	First-time wetsuit buyers	Repeat buyers who know their cut
Risk of wrong fit	Lower if measured carefully	Higher with brand differences
Stretch allowance	Built into the chart	Judged by feel

How the Chart Measurements Compare

The brand chart relies on body measurements rather than a dress-size equivalent, which is the main reason it outperforms guessing. Measure your bust at the fullest point, your natural waist, and your hips at the widest point, all over your skin without a bra or padding. Wetsuit fit depends heavily on torso length and chest volume, so the measurement-first approach wins for most women. Winner: measure-first.

Fit Tolerance and Stretch

Neoprene needs to fit snugly, and the chart already accounts for some compression. A wetsuit that feels loose on land will often let in water at the neck and wrists once you are in the pool or open water. Size-up methods leave this to trial and error. Winner: the chart, because it sets expectations before you buy.

Brand Differences and Cross-Sizing

Women’s sizing is not standardized across manufacturers, so a size medium in one brand can fit like a small or large in another. If you are moving from a different label, compare your measurements to the chart instead of your old size label. Readers who have a dive skin fit guide on hand can see how cut differences show up in practice. For a related sizing reference, see Dive Skin Size Chart: How to Find the Right Fit (2026). Winner: measure-first for anyone switching brands.

Ease of Use for Different Body Types

Women with a larger bust relative to waist often find the chart’s bust measurement more reliable than the overall size label. Shorter or taller torsos can also shift the result, so check the length guidance too. Winner: chart-based sizing for most body shapes, with the size-up method only for experienced repeat buyers.

Pros & Cons

Measure-first (brand chart)

Pro: Gives a clear, repeatable starting size based on your body.
Pro: Reduces guesswork when you buy from a new brand.
Con: Requires careful measuring and sometimes a second opinion on torso length.

Size-up from your usual size

Pro: Quick if you already know how one cut fits.
Pro: Useful when you own several wetsuits and know your preferred stretch.
Con: Often leads to the wrong size when brands differ.

Which Should You Choose?

Choose the measure-first approach if you are buying your first Aqualung women’s wetsuit or switching from another brand. Take your measurements and match them to the chart before ordering. View on Amazon
Choose the size-up approach if you already own an Aqualung wetsuit that fits well and want the same cut again. Compare the new chart to your current garment’s measurements before buying. View on Amazon

FAQ

Should I size up or down from my usual wetsuit size?

Do not assume. Compare your bust, waist and hip measurements to the brand chart first, since different labels fit differently. If your measurements fall between sizes, consider the stretch level and torso length before choosing.

How tight should a women’s wetsuit feel?

It should feel snug across the chest and back with no large gaps at the neck or wrists. Some compression is normal, but you should still be able to breathe deeply and move your arms freely. If you have a medical condition affecting circulation or breathing, consult a professional before diving or swimming in a tight suit.

Can I try on a wetsuit before buying?

Some shops allow fitting in person, which is the most reliable way to check sizing. If you buy online, read the return policy and plan to test the fit in a pool before using the suit in open water.

Conclusion

For most women, the measure-first approach using the brand chart is the safer choice, especially for first purchases or brand changes. Repeat buyers who already know their cut can size up with less risk. Either way, check the fit at the neck, chest and wrists before your first dive.
