How Big Is a 22 Quart Cooler? | Real Dimensions

A 22 quart cooler holds 22 US quarts, about 20.8 liters or 5.5 gallons — enough for roughly 30 cans, though outer dimensions vary by brand.

Whether you’re sizing one for a tailgate, a week of lunches, or the back of your SUV, the quart rating tells you volume, not footprint. Two different 22 quart coolers can look noticeably different side by side because wall thickness and shape vary between manufacturers. Understanding what the number actually means — and how much space you truly get — comes down to a few straightforward measurements.

What Does “22 Quart” Actually Mean?

The quart rating describes interior volume, not the cooler’s outer dimensions. Twenty-two US quarts converts to 20.82 liters or 5.50 US gallons of capacity. That places it in the small-to-medium portable cooler class, but real-world fit depends on how thick the insulation walls are and how the cooler is shaped.

For context, that’s enough space for roughly 30 standard 12-ounce cans, a couple of sandwich containers plus drinks, or about 22.5 pounds of ice. The practical takeaway: always compare external and internal dimensions between models, not just the quart number, when you’re deciding what fits in your vehicle or how much you’re willing to carry.

If you’re weighing which model fits your needs, a roundup of tested top-rated 22 quart coolers compares the leading options side by side.

Two Real 22 Quart Coolers, Measured

To see how much the footprint can vary, look at two current models with the same rated capacity. The RTIC 22 QT Ultra-Light Cooler measures 19.6 inches long, 13.35 inches wide, and 15.98 inches high on the outside. Inside, it offers 13.46 by 9.57 by 12.36 inches of usable space, holds 30 cans, and weighs 11.5 pounds empty.

The Canyon Coolers Outfitter 22qt V2 takes a more compact footprint: 16.5 by 12.5 by 16 inches externally, with an interior of 12.5 by 9.0 by 12.5 inches. It’s heavier at 15.7 pounds, reflecting denser construction rather than a larger size.

That’s a 3-inch difference in length between two coolers with identical capacity ratings. One reason is insulation strategy — RTIC’s Ultra-Light line uses lighter materials to cut weight, while Canyon’s Outfitter prioritizes rugged rotomolded durability. The tradeoff directly affects both the exterior envelope and what you’ll feel when you lift it.

Neither is wrong; they’re designed for different priorities. The table below sums up the key comparisons.

Per RTIC’s official spec sheet, the Ultra-Light’s interior height of 12.36 inches clears most upright 2-liter bottles and tall growlers. The Canyon model’s spec page notes its own dimensions directly on the product listing.

How to Check What Fits Inside

Before you buy, measure what you actually plan to store. Internal dimensions matter more than external ones when you’re checking whether bottles, meal-prep containers, or medical supplies will fit. A common mistake is grabbing a cooler based on the quart rating alone, then discovering your tallest water bottle won’t stand upright.

For vehicle and boat use, also factor in the lid and handles. A cooler’s official height often excludes an open lid or tall handle, which can add several inches when it’s stowed. Canyon’s product page for the Outfitter 22qt carries the full dimensional breakdown for reference.

Portability is a separate question from size. The RTIC weighs 11.5 pounds empty, while the Canyon comes in at 15.7 pounds — a 4-pound gap that matters when you’re carrying a fully loaded cooler any real distance.
