The realistic size
46-inch tool chests, the size that fits an actual garage
Not a compromise. A 46-inch cabinet in 18-gauge steel fits a bay a 56 cannot, and Milwaukee publishes thicker steel here than most of the wider boxes manage.
A 46-inch cabinet is the largest box that fits a single-car bay with the car in it, and it is the size where 18-gauge steel is genuinely available - Milwaukee publishes 18 gauge (0.0478 in) across its High Capacity line, thicker than the 19 or 20 gauge most 56-inch cabinets use.
Why this size deserves better press than it gets
Buying guides treat 46 inches as the step below the real thing, and that is a photograph problem rather than an engineering one. Wider looks better in a listing image. What actually happens in a garage is that a 56-inch cabinet plus caster overhang leaves you sidling past it, and a 46-inch one does not.
The spec sheets back this up. The thickest published body gauge in the mainstream consumer market - 18 gauge - appears on 46-inch cabinets and chests. The trade is a lower published drawer rating on those same units, typically 100 lb per pair against the 120 to 150 lb the wide cabinets publish. Thicker box, more conservative drawers. That is a real choice, not a downgrade.

Top pick · The thickest published steel at 46 inches
Milwaukee High Capacity 46 in. 8-Drawer Roller Cabinet
Milwaukee publishes 18-gauge across the High Capacity line, which is 0.0478 in - 33 percent thicker steel than a 20-gauge body. The drawers are rated lower than the Husky's at 100 lb, so it is a thicker box with more conservative drawers.

What does not

- Amazon listings for Milwaukee storage are third-party and move around
- No published empty weight on the listing, so caster load is a guess

2 · Adding drawers on top of a cabinet you already own
Milwaukee High Capacity 46 in. 8-Drawer Top Chest (48-22-8541)
A top chest, not a standalone: 18-gauge steel, 100 lb soft-close drawers and a published 1,000 lb hold. 15,877 cubic inches is about 9.2 cubic feet, which is the number worth converting before you decide it is enough.

What works
- Publishes gauge, slide rating, total hold and volume - all four, which is rare
- Matches the 46 in cabinet exactly, so the stack lines up
- Soft close on every drawer, not just the deep ones
What does not
- It is a top chest: it needs a cabinet or a bench under it
- No listed empty weight, so you cannot check what the cabinet beneath is carrying
- 100 lb drawers cap what the deep bottom drawer is really for

3 · A shallow bay where 22 inches of depth will not fit
Craftsman S2000 Series 52 in. 8-Drawer Tool Chest (CMST98272)
Craftsman publishes an 18-20 gauge I-frame rather than a single figure, which is a real answer and an annoying one: the frame is thicker than the panels. At 16 in deep it is the shallow option here, which is a virtue in a narrow garage and a limit everywhere else.

- 100 lb80 lb working
- Storage

- Empty weight

What works
- 16 in deep fits a bay where a 22 in box would block the car door
- Publishes a storage volume, which makes it comparable rather than adjectival
- The I-frame spec is honest about mixed gauges instead of quoting the thickest panel
What does not
- 16 in of depth means long tools sit diagonally or not at all
- 18-20 ga is a range, so the thin end is what the panels actually are
- Top chest only - this is not a floor-standing box

Who it is for
A narrow garage, a bench top, or a second chest for shallow hand tools.
What it is not for
Torque wrenches and breaker bars, which need depth this box does not have.

How we picked
- 46 inches as published, plus the 52 in chests that fit the same wall.
- Published gauge first. This is the size where 18 gauge is actually available, which is not true of every 56.
- Drawer rating and volume, converted, so the boxes are comparable.
- Does it stack? At this size the matching top chest matters, because the vertical is how you get capacity back.
What we did not do
Everyone in this category says they spent seventy-five hours testing tool chests. We have not opened any of these boxes, and we say so. What we do instead: compile the published specs, convert the steel gauges, multiply out the slide ratings, cite the maker’s own listing, and show the arithmetic so you can check it. The full method, including how to challenge a figure.
What we would skip
A list with no losers is a list nobody edited. These are the choices we would actively steer you away from, and why.
Assuming 46 inches means budget
It does not. Milwaukee publishes 18-gauge steel on its 46 in High Capacity line, which is thicker than the 19 or 20 gauge on most 56 in cabinets. Narrower is a footprint decision, not a quality one.
Buying 46 inches and then wishing you had bought 56
If you genuinely have five feet of clear wall and long tools, buy the bigger box. This size is the right answer when the space is the constraint - not a consolation prize to talk yourself into. Measure first, then choose. The 56-inch page.
Get your capacity back vertically
The way to make a 46-inch footprint hold as much as a 56-inch one is to stack. A matching top chest adds eight shallow drawers directly above the cabinet without taking another inch of floor, and shallow drawers are exactly what most people are short of - screwdrivers, pliers, measuring tools, everything that gets lost in a deep drawer.
One published 46-inch top chest carries 15,877 cubic inches, which is about 9.2 cubic feet, and states a 1,000 lb total hold. Added to a cabinet, that is a serious amount of storage on a footprint that still lets you open the car door. Top chests covers the format properly.
The 52-inch middle ground
Craftsman's S2000 chests are 51.5 inches wide and only 16 inches deep, which is a genuinely different proposition: nearly the width of a 56 with a footprint shallower than anything else here. In a garage where depth is the constraint - a bay where a 22-inch box would stop the car door opening - that shallow depth is the whole point.
The cost is that 16 inches will not take a long tool lying flat. If your drawers are hand tools and fasteners, that does not matter. If they are breaker bars, it matters a great deal.
Common questions
Will a 46-inch tool chest fit in a single-car garage?
Yes, in most cases with the car still in it. That is the main argument for the size: a 46 in cabinet needs roughly four feet of wall plus standing room, against about five feet for a 56. Measure the wall, then choose.
Is a 46-inch tool box thinner steel than a 56?
Often the opposite. Milwaukee publishes 18 gauge (0.0478 in) on its 46 in High Capacity line, thicker than the 19 or 20 gauge most 56 in cabinets publish. The 46 in units tend to publish lower drawer ratings instead, at 100 lb per pair. The gauge table.
How do I get more storage from a 46-inch footprint?
Stack. A matching top chest adds shallow drawers directly above the cabinet without taking another inch of floor - one published 46 in chest carries 15,877 cu in, about 9.2 cu ft, and states a 1,000 lb hold. Top chests.
