Car ski racks, and the part nobody checks before buying one
A roof ski rack does not attach to a roof. It attaches to crossbars, and whether you have usable crossbars is the whole purchase decision.

The short answer
A roof ski rack mounts to crossbars, not to the roof - so check you have them, or budget for them, before anything else. Then buy on published capacity: Thule publishes 2 pairs of skis (S), 4 pairs or 2 snowboards (M) and 6 pairs or 4 snowboards (L). For one or two trips a year, skis inside the car is cheaper, warmer and does not cost you fuel.

The crossbar problem, first
Almost every disappointed ski-rack buyer made the same mistake: they bought the ski rack and discovered the car needs a roof rack system underneath it.
A ski carrier clamps onto crossbars that run across the roof. What your car has from the factory is usually one of three things:
- Nothing. A bare roof. You need a full roof rack system - feet, fit kit and crossbars - before a ski carrier is even a question, and that system typically costs several times the carrier.
- Raised side rails only. Two rails running front to back with a gap underneath. These are not crossbars. You need crossbars to span them, and those are a separate purchase.
- Factory crossbars. Bars already running side to side. You are ready, but check the spacing - a ski carrier needs the bars far enough apart to support the skis and close enough together to fit the carrier.
Published capacity, which is the easy part
Once the crossbars are sorted, this category is unusually honest: capacity is published as a number of pairs, and the numbers are meaningfully different.
| Size | Skis | Snowboards | Suits |
|---|---|---|---|
| SnowPack S | Up to 2 pairs | Not published for this size | Two adults, no children |
| SnowPack M | Up to 4 pairs | Up to 2 boards | A family of four |
| SnowPack L | Up to 6 pairs | Up to 4 boards | Carpooling, or mixed groups |
Two things the published number does not tell you. Capacity assumes the skis have bindings, which take up most of the width - so four pairs of wide skis is optimistic where four pairs of narrow ones is not. And a snowboard takes the space of roughly two pairs of skis, which is why the board numbers are half the ski numbers.
Locking, which is two separate problems
All three sizes publish locking on both axes, and it is worth understanding why there are two.
- Skis locked to the carrier. Stops someone lifting your skis off a parked car.
- Carrier locked to the crossbars. Stops someone taking the rack with the skis still in it, which is the theft that actually happens.
Neither is a serious deterrent against someone determined and equipped. A roof rack lock is a delay and a discouragement, not a safe. The gear theft page is honest about what locks do and do not achieve, and the short version applies here: never leave gear on a roof overnight in a hotel car park.
The alternatives, honestly compared
| Method | Cost | Downsides | Best for |
|---|---|---|---|
| Skis inside the car | Free | Wet gear in the cabin; seats down; smell | One or two trips a year |
| Roof ski carrier | Carrier plus crossbars if you lack them | Fuel cost; height clearance; snow and salt on gear | Regular trips, full car |
| Roof cargo box | Most expensive | Bulky to store; same fuel cost | Families carrying luggage as well as skis |
| Hitch-mounted carrier | Needs a tow hitch | Blocks the tailgate; road spray | Cars where roof height is a problem |
The row people skip past is the first one. A pair of skis is about 170 cm and most estate cars and SUVs will take them diagonally with a rear seat folded. If you ski twice a year with two people, the correct answer is a ski bag on the back seat and no rack at all. The bags page covers keeping wet gear off the upholstery.
Loading a rack without damaging anything
- Bases together, edges in. Two skis face to face protects both bases and stops the edges reaching the rubber arms.
- Tips pointing backward. Less aerodynamic disruption and less chance of a tip catching wind.
- Alternate tip and tail. A pair of skis is thicker at the binding than at the ends; alternating them lets the arms close evenly.
- Clean before you load. Grit trapped under a rubber arm scratches a topsheet for the whole journey.
- Wax before, not after. Road salt spray on a roof is genuinely hard on edges. The edge care page explains what salt does.
Who should buy what
- Two adults, two trips a year. No rack. Skis inside, in a bag.
- A family of four with skis. The SnowPack M, if you have crossbars.
- Mixed skiers and snowboarders, or carpooling. The SnowPack L.
- A couple who are certain the number stays two. The SnowPack S - read the skip note first.
- Flying rather than driving. None of this. The travel page covers airline baggage rules.
Every pick, with the working
Each entry shows the published inputs, the axis scores they produce, and what you give up. The order is the computed order, not a commercial one, and the arithmetic is open underneath each score.
1 · A family of four with skis, or two snowboarders with room to spare
Thule SnowPack M Ski and Snowboard Rack
The size that fits a family: a published four pairs of skis or two snowboards, locking the gear to the carrier and the carrier to the roof bars. It is the middle of three published capacities and the one most households actually need.

What it gets right
- Published capacity of up to 4 pairs of skis or up to 2 snowboards
- Locks the skis to the carrier and the carrier to the roof bars, which are two separate thefts to prevent
- Soft rubber arms published as gripping without scratching topsheets or bases
- Part of a published three-size range, so the capacity decision is made on a number rather than a guess
What you give up
- Requires roof bars you already own; the rack is not a complete roof system
- No published warranty term on the product page
- Published capacity is the limit with bindings, so four pairs of wide skis is optimistic

2 · Carpooling, or a mixed group of skiers and snowboarders
Thule SnowPack L Ski and Snowboard Rack
The large size, published at six pairs of skis or four snowboards. It is the right buy for a household that regularly carries other people's children, and the wrong buy for anyone whose roof bars are short — the rack has to fit across them before the capacity means anything.

- Same published locking on both axes: gear to carrier, carrier to bars
- Soft rubber arms published as non-scratching
- One rack covers the mixed ski-and-board case that defeats a smaller carrier
What you give up
- Needs wide enough roof bars, and short factory bars are the common blocker
- More rack than a two-person household will ever fill

3 · Two adults who are certain the number will stay two
Thule SnowPack S Ski and Snowboard Rack
Skip this one. The published capacity is two pairs of skis and no snowboard capacity is published for this size at all. That is genuinely enough for a couple - and it is the rack most likely to be replaced rather than kept, because the moment there is a third pair of skis or one snowboard in the household it is the wrong size. If the decision is close, the M costs less than buying twice.
Published at two pairs of skis, which is a couple and no more. It is the cheapest way into the range and the size people most often regret, because a second child arrives with a second pair of skis and the rack does not grow.

Questions people actually ask
Do I need crossbars for a ski rack?
Yes. A roof ski carrier clamps to crossbars running across the roof, not to the roof itself. Raised side rails running front to back are not crossbars - you need bars spanning them, and that is a separate purchase that usually costs more than the ski carrier. Check what your car actually has before ordering anything.
How many skis fit on a roof rack?
Thule publishes up to 2 pairs on the SnowPack S, up to 4 pairs or 2 snowboards on the M, and up to 6 pairs or 4 snowboards on the L. Those figures assume skis with bindings, so wide skis eat the capacity faster than narrow ones, and a snowboard takes roughly the width of two pairs.
Can I just put skis inside my car?
Usually, and for one or two trips a year you should. A pair of skis is about 170 cm and most estate cars and SUVs take them diagonally with a rear seat folded. Use a ski bag to keep wet edges and road salt off the upholstery. A rack only pays for itself when the car is genuinely full.
Does a ski rack affect fuel economy?
Yes, measurably, and more when loaded. Anything on a roof disrupts the aerodynamics at highway speed. The practical answer is to take the carrier off between trips - it takes a couple of minutes, and leaving it on all winter is how people end up paying for the rack twice.
Are ski rack locks worth it?
They are a delay and a discouragement, not a safe. The useful part is that a good carrier locks on two axes: skis to the carrier, and carrier to the crossbars - the second is the theft that actually happens. Never leave gear on a roof overnight in a hotel car park regardless of the lock.
