Divider drawer guide
Divided drawer ideas by room: kitchen, bath, office, shop and closet
Most people meet built in drawer dividers in a flatware drawer and stop there. The same dovetailed box with Baltic Birch dividers in its walls sorts a vanity, a desk, a workbench, a dresser and a boat galley just as well. This guide is for the homeowner with one drawer that drives them mad and the cabinet shop outfitting a whole house: a layout, a box size and the configurator picks for each room.
Quick answer. Built in drawer dividers suit any drawer from 6 to 35 31/32 in wide and 2 to 12 3/4 in tall, not only the kitchen. A vanity drawer takes a 2 row by 3 bay grid for makeup and one 5 in bay for a curling iron, an office pencil drawer a 3 by 4 grid of compartments about 5 x 6 in, a workshop drawer movable dividers on 1 in centers, a dresser drawer 4 1/2 in squares for socks, and a jewelry drawer 49 compartments about 2 1/2 x 2 in. Every one is the same dovetailed box with 0 to 6 Baltic Birch dividers each way, cut to the 1/32 inch.

Divided drawer ideas at a glance
L counts lateral dividers, which run side to side and make rows; A counts axial dividers, which run front to back and make bays; compartments equal (L + 1) x (A + 1). Box sizes are outside sizes with 5/8 in sides after the slide deduction: opening minus 13/32 in (10 mm, often written 3/8 in) for Blum style undermount runners, opening minus 1 in for side mount slides. Compartment sizes are clear sizes between 1/4 in dividers with equal spacing, the figures the live 3D preview’s spec line reports.
The kitchen has its own pages: kitchen drawer divider sizes, knife drawers, spice drawers and deep drawer dividers; this page is about everywhere else.

Bathroom vanity drawers: makeup, hair tools and toothbrushes
A vanity drawer wants two or three rows of mid sized compartments for makeup and one long bay for hair tools. Most vanities are about 21 in deep, which takes an 18 in box on 18 in runners; an 18 in vanity has a 16 1/2 in opening, so the box is 16 1/8 in wide for undermount slides and 14 7/8 in inside. One lateral and two axial dividers make six compartments about 4 25/32 x 8 1/4 in. For a curling iron, about 12 to 14 in long, use the second drawer, 6 in tall, with two axial dividers and custom spacing: one 5 in bay the full 16 3/4 in length for the iron and its cord, and bays of 4 5/8 and 4 3/4 in beside it.
Choose removable dividers so the drawer wipes clean after a spill of powder, and Baltic Birch, which ships finished, for a room full of steam; Hard Maple (Select Grade) ships finished or unfinished, so choose finished for a bathroom.
Office and desk drawers: pens, cables and chargers
A pencil drawer takes a grid of compartments about 5 x 6 in. A 23 5/8 x 20 x 3 in box with two lateral and three axial dividers makes twelve compartments about 5 13/32 x 6 3/32 in: pens, stapler, tape, and coiled charging cables one to a cell so they never knot. For a ruler, choose custom spacing and make one bay the full 18 3/4 in depth. Files belong in a file drawer with rails.
Workshop and garage drawers: small parts and hand tools
Hardware wants many small fixed compartments; hand tools want a few wide bays you can move. A 29 x 22 x 3 in box, built for side mount slides 1 in narrower than its opening, with five dividers each way makes 36 compartments about 4 13/32 x 3 1/4 in for screws, nuts and fittings by size. For tools, a 29 x 22 x 5 in multi groove box on 1 in centers with six loose 1/2 in dividers gives seven bays you reset as the tools change. Order 1/2 in dividers and a 1/2 in bottom for anything made of steel.
Shop drawers get heavy, and we make no load claim for the box itself, so pick the slide by the maker’s rating: Würth rates the PRO100 side mount slide at 100 lb, and it is in our side mount slides shop. Leave “Notching” on “None” for side mount.
Closet and dresser drawers: socks, ties, belts and jewelry
Rolled socks and folded underwear sort into compartments about 4 1/2 in square, rolled ties and belts into 3 1/2 in squares. Dressers run on wood runners or side mount slides, so measure the drawer that is there and give us the outside size you want. A 30 x 16 x 6 in box with two lateral and five axial dividers makes 18 compartments about 4 19/32 x 4 3/4 in for socks; three lateral and six axial make 28 at 3 29/32 x 3 1/2 in for ties. A 20 x 16 x 2 1/2 in jewelry box with six dividers each way makes 49 compartments about 2 15/32 x 1 29/32 in, our smallest grid, with 1 in dividers so you can see into every one.
Laundry room drawers: pods, sheets and stain sticks
A laundry drawer wants a few deep compartments rather than many small ones. A 16 1/8 x 21 x 6 in box for an 18 in cabinet with one lateral and two axial dividers makes six compartments about 4 25/32 x 9 3/4 in for pods, dryer sheets, stain sticks and clothespins. Choose removable dividers so a burst pod is a wipe, and Baltic Birch, which ships finished, for a damp room.
Craft room drawers: markers, tape and scissors
Markers and brushes lie in bays about 4 in wide; tape, glue and scissors take the row behind. A 23 x 22 x 3 in box with one lateral and four axial dividers makes ten compartments about 4 5/32 x 10 1/4 in. Craft drawers change with every project, so removable dividers or a multi groove box on 2 in centers earn their keep here.
RV and boat galley drawers: small, odd and on the move
Galley drawers are narrow, shallow and never a stock size, and everything in them rattles on the road. We build boxes from 6 in wide and 9 in deep, cut to the 1/32 inch, so an 11 x 15 x 3 in box with two axial dividers gives three bays about 3 3/32 x 13 3/4 in for flatware that stays put. Choose fixed dividers, glued into their dados, and add a “Scoop Front” if the drawer sits behind a door with no handle; the drawer slide types page covers galley slides.
What to pick in the configurator, room by room
Every drawer on this page is one build on the custom divided drawer box page. Enter the outside size in “Width (Inches)”, “Height (Inches)” and the depth fields, then set the counts and style below. Names are exactly as the page prints them; “1/4″ thick dividers (our standard)” is the thickness unless a row says 1/2 in.
| Drawer | “Lateral dividers (side to side)” | “Axial dividers (front to back)” | “Divider style” | Other picks |
|---|---|---|---|---|
| VANITY, MAKEUP | “1 lateral divider” | “2 axial dividers” | “Removable in dados (slide out)” | “Notching” to “Notched & Drilled For Undermount Slides”, “Depth Selection” to “18” Inches (D)” |
| OFFICE | “2 lateral dividers” | “3 axial dividers” | “Fixed in dados” | “Height (Inches)” to “3” Inches (H)” |
| WORKSHOP, HARDWARE | “5 lateral dividers” | “5 axial dividers” | “Fixed in dados” | “1/2″ thick dividers”, “Notching” on “None” |
| WORKSHOP, TOOLS | “0 lateral dividers” | “6 axial dividers” | “Multi groove front and back (movable)” | “Groove spacing” to “1” centers”, “1/2″ thick dividers”, bottom to “1/2″ Thick Baltic Birch Bottom” |
| DRESSER, SOCKS | “2 lateral dividers” | “5 axial dividers” | “Fixed in dados” | “Notching” on “None”, outside size as measured |
| JEWELRY | “6 lateral dividers” | “6 axial dividers” | “Fixed in dados” | “Divider height” to “Custom divider height”, 1 in “Custom divider height (inches)” |
To order several drawers with different layouts, build the first, add it to the cart, then build the next. The configurator opens with “1 axial divider”; if both counts are 0 the preview shows a red warning and Add to cart is held, because a plain box is our custom drawer box. The configurator guide explains every field.

Divided drawer questions, room by room
Can a bathroom vanity drawer have built in dividers?
Yes. A vanity drawer is a normal drawer box to us, usually 18 in deep for an 18 in runner, and it takes 0 to 6 Baltic Birch dividers each way like a kitchen drawer. A 16 1/8 x 18 x 4 in box for an 18 in vanity with one side to side and two front to back dividers gives six compartments about 4 25/32 x 8 1/4 in for makeup and brushes. Choose removable dividers so the drawer wipes clean.
Can you build dividers into a dresser drawer?
Yes. Give us the outside size of the box you want, since dressers run on wood runners or side mount slides rather than kitchen undermounts; with side mount slides the box is 1 in narrower than the opening. A 30 x 16 x 6 in box with two side to side and five front to back dividers makes 18 compartments about 4 19/32 x 4 3/4 in for rolled socks and underwear.
What divider layout works for a workshop drawer?
Multi groove on 1 in centers with 1/2 in dividers and a 1/2 in bottom. The six loose front to back dividers drop into any groove, so the bays change as tools come and go, and the thicker dividers stand up to steel. Run it on side mount slides rated by the maker, such as the Würth PRO100 at 100 lb, with the box built 1 in narrower than the opening.
Do drawer dividers work in shallow drawers?
Yes, down to our 2 in minimum box height. As standard the divider tops sit 1/8 in below the top of the box, so a 2 in box gets 1 7/8 in dividers, and a custom height can be as low as 1 in. Shallow divided drawers suit jewelry, pencils, cosmetics and small parts.
Can I order several drawers with different layouts?
Yes. Each drawer is its own build in the configurator, so set the size and layout for one, add it to the cart, then build the next; each one is its own line in the order. If you email sketches for custom spacing, say which drawer each sketch belongs to along with the order number.
What finish should a bathroom or laundry drawer have?
Baltic Birch, which ships finished, is our suggestion for a steamy bathroom or a laundry room. Hard Maple (Select Grade) ships finished or unfinished, so choose finished if it is going somewhere damp. Either way, wipe up water rather than letting it sit, and remember the dividers are Baltic Birch plywood in both woods.
