Parents come in with the same question most weeks. Their daughter needs shorts for netball or athletics, someone at the club mentioned Nike Pro, and now they are standing in front of three different lengths with no idea which one is right.

Nike Pro is not sized the way a normal pair of shorts is sized. It is compression wear, which means fit does a different job to regular shorts, and getting it wrong is easy without someone explaining how the sizing works.

We get this question at the counter constantly, so here is the breakdown we would give in person.

Bike Shorts, Tights Or Full Leggings

The three formats cover different situations, and the length is the whole decision.

A bike short sits around 3 inches, ending high on the thigh. It gives full compression and range of motion with nothing flapping, which is why it is the standard for netball, athletics and anything involving sprinting or jumping. The Nike Pro girls' bike shorts we stock run to that 3 inch length in a stretch fabric built for exactly that kind of movement.

Tights run to the knee or mid calf and suit training sessions, gym work and anything where a bit more coverage matters, cold mornings included. Full length leggings go to the ankle and work best for running, cycling or lower intensity training where warmth counts for more.

If your kid is playing a fast-moving sport with a lot of direction changes, start with the bike short. If they are training rather than competing, tights or full length usually suit better.

What Compression Sizing Means

Regular clothing sizing gives you room. Compression sizing does the opposite, and that catches a lot of people out the first time they buy Nike Pro.

The fabric is designed to sit close to the skin and hold its shape, which means a size that feels snug in the changing room is usually the right one. Sizing up because it feels tight defeats the purpose. Loose compression wear does not compress, it just moves around during play, which is worse than wearing a slightly firm fit that stays put.

The Nike Pro Dri-FIT leggings we carry use the same wide elastic waistband as the bike shorts, sitting flat against the skin rather than digging in or rolling down. That waistband is doing a lot of the work, so check it lies flat rather than gapping before deciding a size is wrong.

Girls' Sizing Versus Women's Sizing

This is where families ask the most questions, and it is worth explaining properly rather than guessing.

Girls' Nike Pro sizing generally covers school age through early teens, and the cut is built for a younger frame through the hip and waist. Once a teenager grows into an adult body shape, women's sizing tends to sit better through the same areas, even if the number on the label looks close to what they were wearing before.

The safest approach is trying both ranges around the transition age rather than assuming girls' sizing stops working at a particular birthday. If your daughter has recently had a growth spurt, it is worth trying a size up in girls' before jumping straight to women's, since the girls' range often has room at the top of its size run that people do not expect.

Worth knowing too: girls' Nike Pro and the Nike women's bike shorts we stock sit differently through the waist, with the women's cut running mid rise rather than the low, sport-specific waistband on the girls' version. If your daughter is between ranges, that waist height is worth comparing before length.

Dri-FIT And Why It Matters

Every Nike Pro piece we stock uses Dri-FIT fabric, and it is the reason these shorts get chosen over a basic cotton pair for sport.

The fabric pulls sweat away from the skin and spreads it across a wider surface so it evaporates faster. On a warm Saturday morning at the courts, that is the difference between a short that feels heavy by the second quarter and one that still feels dry. It is a genuinely different fabric to a plain polyester short, and it is why serious training gear costs a fair bit above a basic pair from the supermarket.

The Squat Test

Nobody writes about this, but every parent and player checks it. Before you commit to a size, have your kid do a squat and a lunge in the changing room. Compression fabric should stay opaque and stay put through that movement. If it goes see-through at the seat or the waistband rolls down when they bend, size up rather than assuming it will settle with wear.

This matters most for darker colours under bright gym lighting, and it is a two-minute check that saves a return.

Building The Rest Of The Kit

Once the base layer is sorted, the rest of an activewear outfit follows the same logic: fabric that moves sweat, a fit that stays put, and layers that come off easily between drills. If you are putting together a wider casual and sport wardrobe for a teenager rather than just sorting one pair of shorts, our guide to women's streetwear outfits in NZ covers how to make activewear pieces work off the court as well as on it.

Bring your kid in and try before you buy where you can. Compression fit is one of those things that photographs well online and still surprises people once it is on, and two minutes in a changing room beats guessing from a size chart every time.
