A 16″ cabinet does not hold a 16″ shirt

Here is a thing that catches people out on their first few jobs. You build the run at 16" deep, which is right, and you hang the customer's clothes in it, and the clothes stick out past the front of the cabinet by another five or six inches.

Nothing is wrong. That is what a closet looks like. But it is worth knowing before you draw, because there are four or five places in a layout where those five inches decide whether the job works.

The cabinet depth is not the clothes depth

A run depth of 16" is the working figure, and it is what a new job starts at here. It is not chosen to fit a garment. It is chosen because it is a good use of a sheet, it keeps the shelf reach sensible, and it leaves the room in front of it usable.

What hangs off the rod is deeper than that. Shoulder to shoulder, on the hanger, with the garment on it, you are five to six inches past the face of the cabinet. Heavier things are worse: a winter coat, a suit jacket with structure in the shoulder, anything on a thick wooden hanger.

So the honest way to think about a hanging section is about 16" of cabinet and about 21" or 22" of occupied air.

This is a hanging problem and nothing else. A shelf bay at the same 16" is 16", full stop: folded goods, boxes and baskets all sit inside the carcass. Drawers are inside it by definition. Shoes on a pitched shelf are inside it. The only thing in a closet that lives in front of the cabinet you built is a garment on a hanger, which is why a run of shelves and a run of hanging read the same on the drawing and take different amounts of room in the house.

The carcass is what you cut. The clothes are what you have to leave room for. Those are two different numbers, and only one of them is on the cut list.

Where those inches do not matter

Most of the time, nowhere. In an ordinary reach-in the room is about 24" deep wall to wall and the cabinet is 16", so the garments live in the eight inches in front of the run, which is exactly the space that was there for them. Nobody notices, because there is nothing for them to be in the way of.

That is the normal case, and it is why the standard depth is standard.

Where they do matter

A door on the closet, in front of a hanging run. A bi-fold or a sliding leaf runs in front of the opening, not in front of the cabinet. If the track sits tight to the cabinet face, the clothes are what the door catches on. In front of shelves the same track clears fine. This one produces a callback, because it is fine on the day and annoying every day after.

Two runs facing each other in a walk-in. The walkway between them is not the gap between the cabinets. It is the gap between the clothes, which is the gap between the cabinets less about a foot once both sides are loaded. Draw a 36" walkway between two hanging runs and the customer is walking down 24" of it.

An island. Same arithmetic, and the same rule of thumb: leave about 36" around it. Where the run beside it is hanging, measure to the clothes and not to the carcass, or a walk-in that looked generous on the plan is one you have to turn sideways in. Where it is shelves, the carcass is the edge.

An inside corner. The corner rule already holds the second run back by the depth of the first plus 10", so this is mostly handled for you. It is worth knowing why the number is what it is: hanging clothes in a corner are unreachable well before the cabinet is.

A tight reach-in with a rod in it. If the room is under about 24" deep, a 16" hanging run puts the clothes into the doorway. That is the case where you drop the run depth rather than accept it. The same room full of shelves at 16" is fine.

What to do about it

Three answers, in the order you should reach for them.

• Accept it. In a reach-in with a normal opening this is right. The clothes stick out, the door closes, nobody thinks about it again.
• Draw the room honestly and let the plan show you. Put the real outline in, put the door where it actually is, and look at the walkway you are left with rather than the walkway between the cabinets.
• Go deeper, and know what it costs. Depth is a job default and any single tower can override it. A deeper carcass eats more sheet, pushes the shelf reach further, and gives back less than you would think, because you are chasing a garment that is not much past 22" whatever you do.

What you should not do is go shallower to save material on a hanging section. Take the run under about 14" and the hanger hook starts riding off the front of the rod, and the clothes hang crooked. Shallow is for shelves and shoes, not for hanging.

The short version

A hanging section takes more room than the cabinet you cut for it. Sixteen inches of carcass, five or six inches of clothes past the front. A shelf section at the same depth takes exactly what it measures. Everywhere you measure a clearance in a closet, a doorway, a walkway, an island, ask whether you are measuring to the panel or to the shirt. The panel is on the drawing. The shirt is what the customer walks into.
