How To Size Skis, Boots, Poles and Other Gear

Learn how to size skis and ski gear correctly to reduce guesswork when shopping online.

Key Takeaways

• Proper ski sizing depends on your height, weight, and skill level. 
• Unlike street shoes, ski boots use Mondopoint sizing for a snug fit.
• To find the perfect ski pole length, use the 90-degree test.

Buying ski gear through an online sportswear store can be convenient, but skiing isn’t forgiving when equipment doesn’t fit right. Skis that are the wrong length, boots that feel off, or poles that don’t match your stance can all affect how you move on the mountain. Before you add anything to your online shopping cart, it’s important to understand how to size skis and other gear properly and what measurements actually matter. 

How To Choose the Right Ski Size

Skis don’t come in one size, so how do you know what size to buy? You need to find skis that fit you and your skill level. To start, stand the ski upright next to you. The tip of the ski should reach somewhere between your chin and the top of your head. 

Youth sizes follow slightly different rules. For very young kids (under age 6), the ski tips might come up somewhere between their chest and chin. Older kids (up to early teens) typically do well with skis that reach between their chin and nose.

You also need to consider your weight. If you’re lighter than average for your height, choose a ski on the shorter end of that range. If you’re heavier, a slightly longer ski can provide better support and stability.

Consider Your Skill Level

Beginners and less experienced skiers should lean toward shorter skis, which are easier to turn and control at slower speeds. Advanced or aggressive skiers often prefer longer skis for more stability at higher speeds.

Think About Your Skiing Style

Do you enjoy quick, short turns and skiing in tight spots like moguls or among trees? If so, go with shorter skis for easier maneuvering. 

If you love going fast, making long sweeping turns, or floating in powder on open slopes, longer skis will feel more stable and give better floatation in deep snow.

When in doubt, err on the shorter side. A ski that’s slightly too short is easier to handle than one that’s too long, especially for beginners. Very long skis can be difficult to control if you’re not used to them.

How To Size Ski Poles Properly

Having the right length ski poles helps you maintain balance and timing while skiing. Sizing ski poles is straightforward:

Use the 90-Degree Elbow Test 

Wear your ski boots or shoes and stand upright. Flip the pole upside down, and grab it just underneath the basket (the small disk near the tip). 

With the pole tip pointing up and the handle on the ground, your elbow should bend at a 90° angle when you hold the pole this way. In other words, your forearm should be parallel to the ground.

If your elbow is bending less than 90° (meaning your forearm angles upward), the pole is too long. If your elbow bends more than 90° (forearm angles downward), the pole is too short.

Refer to a Height Chart 

The length of your ski poles is often given in inches or centimeters based on your height. For example, if you’re about 5 ft 6 in tall, you’d use roughly a 46-inch (115 cm) pole. 

If you’re 6 ft tall, a common pole size is around 50 inches (125 cm). Sizing charts can give you a quick reference, but the 90° test is the best confirmation.

How To Size Ski Boots 

Unlike street shoes, ski boots should fit snugly. Ski boots use Mondopoint sizing, which is based on the length of your foot in centimeters. To measure, stand on a piece of paper with your heel against a wall. Mark the tip of your longest toe, then measure from the wall to the mark in centimeters. That number is your ski boot size. Measure both feet and use the larger number if they’re slightly different.

Here are a few other tips to keep in mind:

• Wear the right socks: Always try on ski boots with thin ski socks, not thick or layered socks. 
• Check your stance: Buckle the boots and bend your knees into a skiing position. When you lean forward, your toes should pull slightly back from the front of the boot. Your heels should stay in place and not lift when you flex.
• Avoid sizing up for comfort: Ski boots loosen slightly as you use them, so it’s better for them to start snug rather than roomy. If a boot feels too comfortable right away, it’s probably too big.

Remember, a ski boot that’s too loose can make skiing harder, while one that’s too tight can cause pain.

How To Measure Your Ski Helmet Size

You’ll need to measure your head for helmet sizing. Take a flexible tape measure (or a piece of string you can later measure against a ruler). Wrap it around your head about 1 inch (2–3 cm) above your eyebrows, above your ears, and around the back of your head at the widest point.

Ensure the tape is level around your head. Imagine a line circling your head mid-forehead and just above the ears. Don’t pull it too tight; it should be snug but not squeeze your head. If you have very thick or puffy hair, or if you plan to wear a thin beanie under your helmet, measure with that in mind (you might add ~1 cm to account for the extra bulk).

Helmet sizes usually come in ranges (such as Small, Medium, Large, etc.), each covering a few centimeters of head circumference. Compare your head measurement to the ski helmet’s size chart. 

Here’s a quick cheat sheet for typical ski helmet sizing:

• 52–55 cm is Small
• 56–59 cm is Medium/Large
• 60–63 cm is Large/XL

These ranges can vary, so always check the specific chart for the helmet you’re considering.
