Storage bin sizes, in real dimensions

Storage bins are sold in gallons and quarts. Garages are built in inches. Nearly every bin problem in a garage comes from that mismatch: the tote that will not fit the cabinet, the stack that overhangs the rack, the shelf that holds four bins when you measured for five.

This page is the conversion. Every dimension below is the manufacturer's published figure, read on the verification date, with no estimates. The rest of the category is in the bins hub.

The dimensions chart

The row that causes the trouble is the fourth one. A 27-gallon tote is 19 5/8 inches wide — call it 19.6 — and that single figure is the reason so much garage storage does not fit together.

Why 19.6 inches matters so much

The 27-gallon tote became the default garage bin, so the rest of the garage gets measured against it whether the manufacturers intended that or not.

The cabinet rows are the expensive lesson. A cabinet is measured on the outside and loaded on the inside, and an 18 in cabinet has perhaps 17 in inside once you allow for the door and back panel. It cannot take a bin that is 19.6 in wide, and no amount of pressing on the door changes that. The depth argument in full is in garage cabinets with doors.

Volume is not the useful number — weight is

A 50-gallon tote holds nearly twice what a 27 holds. What that means in practice is that you will fill it, and then you will not be able to move it.

The practical rule most people arrive at eventually: big bins for light bulky things, small bins for heavy dense things. Holiday decorations and camping bedding go in the 50; bolts, hand tools and paint go in the 18 or smaller. Getting that backwards is how a bin ends up permanently on the floor because nobody can lift it back up.

Stacking: shared lids are the hidden spec

Sterilite publishes something buyers rarely look for and should: which sizes share a lid. The 12 qt and 20 qt use the same lid. The 26 qt and 50 qt ShelfTotes share one. The 12, 18 and 26 gal Latch and Carry sizes all share a lid, and the 50 gal stacker shares with the 200 qt.

That matters because a shared lid means the two sizes stack in the same footprint — a small bin sits square on a big one instead of balancing on a ridge. If you are buying bins in more than one size, buying within one lid family is the difference between a stable column and a leaning one.

Matching bins to shelving

Two figures decide whether a bin works on a shelf: the shelf depth against the bin width, and the shelf clearance against the bin height.

Sterilite's 5 Shelf Unit publishes 15.77 in between shelves. Against that clearance:

• 27 gal industrial tote (15 1/2 in tall) — fits, with about a quarter inch to spare. Tight enough to be annoying if the lid is domed.
• 27 gal stacker tote (19 3/8 in tall) — does not fit. Same gallons, four inches taller.
• 50 qt ShelfTote (14 3/4 in tall) — fits, and Sterilite states it is designed to.
• 18 gal latch tote (13 5/8 in tall) — fits with room over.

That is the whole trap in one list: two bins with identical stated volume can differ by four inches in height. Buy by dimension, then check the gallons. The shelving side of this is in garage shelving that fits your totes.

Matching bins to overhead racks

Overhead racks are usually 24 in or 48 in deep, so the width of a tote is rarely the problem. The constraint is the drop height — the gap between the rack deck and the ceiling — and the height of the bin plus its lid.

A 27 gal industrial tote at 15 1/2 in tall clears a 12 in drop rack only if the bins sit below the deck rather than on it. The full fit table for common rack drops is in which bins fit an overhead rack.

How many bins fit a shelf

This is the arithmetic people do in the aisle and get wrong, because they divide by the gallons instead of the inches. Take a common 36 in wide by 18 in deep shelf:

Two things fall out of that table. First, the biggest bin is often the least efficient — a 50 gal tote does not fit a standard shelf at all, so it ends up on the floor, which is where bins go to be forgotten.

Second, turning a bin changes everything. The 50 qt ShelfTote is 19 7/8 in on its long side and 15 1/2 in on its short one; turned short-side out, two fit a 36 in shelf with room, and the depth is comfortable. Sterilite designed that size around shelving and it shows.

Lid type matters more than the bin

Bins fail at the lid far more often than at the box, and there are three kinds in a garage:

• Recessed lids — the lid sits down inside a lip so the bin above locates on it. This is what makes a stack stable, and it is why Sterilite publishes which sizes share a lid.
• Latching lids — clips at the ends. Worth it for anything that gets carried, and essential for anything you do not want opened by a curious child or a rodent.
• Loose or domed lids — the cheapest, and the reason a stack leans. A domed lid also steals shelf clearance you measured for.

One more consideration nobody mentions on the box: a bin stored under an overhead rack or on a top shelf collects dust on the lid, and that dust arrives inside the bin the moment you open it. Latching lids with a gasket help; a sheet of cardboard over a run of bins helps more and costs nothing.

Clear or opaque

Clear bins let you see the contents, which sounds decisive until you have a shelf of them. In practice, clear works for the bins you open often and matters very little for the ones you open twice a year — those need a label, not a window.

Two honest downsides to clear: it shows the mess inside, so a wall of clear bins never looks tidy, and translucent plastic passes light onto whatever is inside. In a garage with a window, that matters for anything that fades or degrades in UV. Opaque with a good label is the better default for long-term storage, and the labeling system that survives is in labeling a garage bin system.

Which size to actually buy

Most garages need two sizes, not five. A workable default:

1. 27 gal industrial totes as the main unit, because they fit an 18 in shelf, they fit a 24 in rack, and the garage world is built around them.
2. 18 gal or 50 qt totes for anything heavy, because you can still carry one down a ladder.
3. 20 qt boxes for the sorted small stuff that would otherwise rattle around the bottom of a big bin.

Buy one size family at a time and buy several of the same one. Mixed bins do not stack, do not line up, and turn a shelf into a puzzle. The picks themselves are ranked in the best garage storage bins, and the labeling system that keeps any of it working is in labeling a garage bin system.

What we could not verify

• Load ratings for bins. No manufacturer here publishes a maximum contents weight or a stacking load limit, which is a real gap when the instruction is "heaviest at the bottom".
• Filled weights. The weight table is planning arithmetic, not measurement.
• Lid height above the rim. Published heights generally include the lid, but the pages we read do not always state it explicitly, so allow a little clearance when a fit is close.
• Cold-weather brittleness. Plastic gets brittle in hard frost and nobody publishes a temperature range for these bins.
