The most common reason a drawer organizer gets returned is that it does not fit. Not because the product was wrong, but because the drawer was measured from the outside, or not at all. Here is the two-minute version that gets it right.

Measure the inside, not the front

Open the drawer fully. Measure the inside width from the left inner wall to the right inner wall. Drawer fronts are often an inch or two wider than the box behind them, so a drawer that looks 15 inches wide may have 13.5 inches of usable space.

Depth: front to back, minus the slides

Measure from the inside of the drawer front to the inside of the back panel. Some drawers have a bar or slide hardware that intrudes at the back; measure to that, not past it.

Height: the one everyone forgets

Measure from the drawer bottom to the underside of the desk top or the drawer above, with the drawer pushed in. A tray that is 2.5 inches tall will not fit a drawer with 2.25 inches of clearance, and you will only find out when the drawer jams.

Write it down as W x D x H

Our drawer organizer pages list the inside dimensions the organizer needs in the same order. If your numbers are equal or larger on all three, it fits.

When the drawer is an odd size

An expandable organizer covers a range, typically 13 to 21 inches wide, and fills the gap on either side. For drawers that are shallow front to back, a set of small bins in two or three sizes tiles better than a single tray because you can leave out the piece that does not fit.

Kitchen and bathroom drawers

Same method. Kitchen drawers are usually deeper (front to back) than desk drawers, so a tray sized for a desk may leave space at the back. Fill it with a bin rather than leaving a gap where things slide.
