How to size ski gloves and mittens, for adults and children

The measurement, and why it is the only one

Wrap a soft tape around your dominant hand at the widest point across the knuckles, with the thumb tucked out of the way, and read the circumference in inches. Almost every glove brand publishes its size chart against that one number. Hand length is sometimes offered as a secondary check, but knuckle circumference is the figure that decides whether your hand goes in.

Use your dominant hand, which is usually the larger of the two, and buy for that one. A glove that fits the smaller hand and squeezes the larger one is uncomfortable within an hour, and pressure at the base of the fingers is one of the direct causes of cold hands.

How many sizes a brand publishes matters as much as the chart itself. Among the gloves in this ledger, Burton publishes five sizes for the Profile from XS to XL, OutdoorMaster publishes four from S to XL, and the kids version publishes three youth sizes. A five-size run means the boundaries are closer together and you are more likely to land cleanly inside one.

What a correct fit feels like

Put the glove on and make a fist. You should feel the glove resist slightly and then close. Now straighten your fingers: there should be roughly a quarter inch of empty material beyond your fingertips, not a full knuckle’s worth. Pinch the fingertip material and pull; a small amount of movement is right, and being able to pull a half inch of empty glove off the end means it is too long.

The reason for the tight tolerance is thermal rather than dexterity. Your fingers warm the air inside the glove, and that warm air is the insulation. Too much empty volume and your fingers are trying to heat a room. This is why so many people who buy a bigger glove hoping for warmth get the opposite, and it is the same mechanism explained on the cold hands page, which goes through the other causes in order.

Gauntlet or under-cuff, and why you have to pick before you buy

This is a compatibility decision with your jacket rather than a sizing one, and it is the detail most first-time buyers miss.

• Gauntlet cuff. A wide cuff that goes over the outside of your jacket sleeve and cinches down. Better at keeping snow out in deep snow and on falls. Bulkier, and it has to be big enough to clear your sleeve.
• Under-cuff or short cuff. A close cuff that tucks inside the jacket sleeve. Less bulk, easier on and off, and it relies on the jacket cuff sealing over it. This is the style most work gloves use, which is why the Carhartt work glove on this site is noted as having no gauntlet.

Either works. What does not work is a short-cuff glove with a jacket whose sleeve is too short to seal over it, which leaves a gap at the wrist that fills with snow on the first fall. The jacket sizing page covers sleeve length; check the two together.

Sizing a child, which is where this goes wrong

Children’s gloves are the item families most often buy a size up, on the entirely reasonable grounds that the child is growing. It backfires for two reasons at once. The thermal reason above applies with more force to small hands, which produce less heat to begin with. And a glove with loose fingertips makes a child unable to grip a pole or pick anything up, which produces the sulk that ends the morning.

Take the smaller size, and spend the difference on a second pair. A child’s gloves are wet by lunch and there is no drying them on a mountain, so a dry second pair in the bag is worth more than any feature on the first pair. Both kids gloves in this ledger publish named 3M Thinsulate insulation, and the OutdoorMaster kids version publishes a two-year warranty, which almost nothing in the category does.

For genuinely small children, mittens beat gloves outright. Small fingers in separate compartments lose heat fast, a mitten is warmer at the same insulation, and a toddler can get a mitten on without help. Look for a long knitted cuff, which is what actually stops snow going up a sleeve. The toddler gear page goes into the age band where that matters most.

Handing gloves down

Gloves are one of the better hand-me-down items, because they wear at the palm rather than losing performance invisibly the way a helmet does. Check three things before passing a pair down: that the palm has no split seam, that the cuff elastic still closes, and that the inner lining has not pulled loose from the fingertips, which is the failure that makes a glove impossible to put on. The hand-me-down page has the full list by item.

The same logic your boots follow

If any of this feels familiar it is because it is the same principle that governs ski boots and ski socks. Warmth comes from a close fit with a thin layer of still air, not from volume. A thick sock makes a boot colder. A loose glove makes a hand colder. An oversized jacket lets warm air escape at the hem. The whole layering system on the what-to-wear page is built on that one idea.

Before you order

• Measure knuckle circumference on the dominant hand and use the maker chart, not a generic one.
• Check how many sizes the brand publishes. A four-size run has wider bands than a five-size run.
• Decide gauntlet or under-cuff, and check it against the jacket you already own.
• For a child, take the smaller size and budget for a second pair.
• Check whether the maker publishes a warranty term at all. Most glove brands do not; the ones that do are stating something.

Once the size is settled, the glove roundup ranks the field on published insulation, warranty and construction, and the gloves-versus-mittens page settles the format question.
