How Deep Should a Reach-In Closet Be? The Sources Disagree

How deep should a reach-in closet be? Four sources publish 24 inches, and one of them means something different by it.
Closet World, Dimensions.com and Angi describe 24 inches as comfortable, typical or sufficient. Hunker calls it the standard minimum. Those are two different claims, and only one of them tells you that going below it stops working. Below 24, the three sources that publish a figure at all draw the line in three different places: 22, 20 and 18 inches.
- 24 inWhere all four sources converge, for three different reasons
- 22 inHunker: under this, clothes will not hang
- 20 inDimensions.com, as narrow as it goes, if desired
- 28 inHunker, for coats or other bulky hanging items
Every figure on this page is the depth of the closet cavity, measured from the back wall forward. It is not the depth of a shelf board fixed inside it, which runs 12 to 24 inches and is covered on closet shelf depth.
The two happen to share a figure at 24, which is exactly why people mix them up and end up ordering a shelf that fills the whole closet.

How deep should a reach-in closet be, by source
18 to 28
Four sources, one number they all publish, and four different things they mean by it. Put them on the same scale and the disagreement becomes the useful part: 24 is where everybody lands, but only Hunker treats it as the floor rather than the norm.
Typical and minimum are two different claims
24 in
Three sources call it normal
Closet World, Dimensions.com and Angi describe 24 inches as comfortable, typical or sufficient. Closet World adds what the depth does for the clothes: reach-ins are “typically about 24 inches deep, allowing for comfortable storage without clothes brushing against the back wall.”
24 in
One calls it the floor
Hunker writes “The standard minimum depth for a reach-in closet is 24 inches.” Read as a minimum, that figure says something the other three do not: that below it, things start failing.
Below 24
Each source draws its own line
Hunker, Dimensions.com and Angi each put it in a different place, at 22, 20 and 18 inches. Closet World publishes no figure under 24 at all.
28 in
Deeper, for coats
Hunker notes a closet meant for “coats or other bulky hanging items may need to be as deep as 28 inches.” A coat on a hanger is thicker than a shirt, and that is the whole of it.

| 24 in | “plenty for most” | Angi |
| 24 in | “the standard minimum depth” | Hunker |
| 22 in | below it, “isn’t deep enough to allow hanging clothes” | Hunker |
| 20 in | “as narrow as 20 can be used if desired” | Dimensions.com |
| 18 to 24 in | the Standard row of its size table | Angi |
| 28 in | for “coats or other bulky hanging items” | Hunker |

The figures next to this onethe shelf, the width, and what fits in the depth
Alongside this one: closet shelf depth for the board inside the closet, and reach-in closet dimensions for the width and the rod heights that go with this depth. To take the measurement yourself, how to measure a closet says exactly where to stop the tape, and why the depth gets taken twice.
What fits in that depth
Once you have measured it, which systems fit a reach-in takes it from there, and closet systems covers the four families. Taking the door off is a separate option: open closets. If the closet is under four feet wide as well as shallow, see narrow closet layout.
