Kitchen Cabinet Molding Types: Crown, Light Rail, Toe Kick and Quarter Round

There are six cabinet molding types most kitchens need: crown molding along the top of the wall cabinets, a starter or extension strip under the crown, light rail under the uppers, toe kick across the base plinth, quarter round or shoe molding where the kick meets the floor, and scribe and corner trim wherever a cabinet meets a wall. In Fabuwood's Allure Galaxy finishes, a 10×10 kitchen's trim list runs from about $560 with open tops to about $1,380 with crown on a starter strip, every piece ordered in the cabinet finish, by the stick.

We sell cabinets for a living, and molding is where we see the most order mistakes: a crown taller than its gap, no starter strip to fasten it to, light rail forgotten until the LEDs glare. Below are each piece's section size from the manufacturers' spec books, its price on our site, and how the crown pieces stack.

Key Takeaways

• Size crown to the gap, not the room. Measure from the top of the wall cabinet to the ceiling. Fabuwood's crown profiles are drawn from 2⅛″ (CM-3) to 5½″ (CM-8); pick one whose height plus the ¾″ starter is no taller than the gap.
• Crown needs something to fasten to. Fabuwood's spec book calls for STRM-8 starter molding (2½″ × ¾″, $133.25 in Galaxy) under crown on its Allure wall cabinets, so budget it with the crown.
• Bigger gaps take the 6″ MEX-8 extension ($289.25); past about a foot, use a taller cabinet or a stacker.
• Light rail is non-negotiable with under-cabinet lighting. Galaxy LRM is $149.50 and drawn as a ¾″ × 1½″ section; other lines draw theirs from about 1³⁄₁₆″ to 2¼″ tall.
• Toe kick on Fabuwood is 4½″ tall; the TK8 skin is $55.90 per 8-foot stick. Quarter round (QRM, $62.40) is a ¾″ quarter circle; shoe molding is the flatter, taller-than-deep version.
• Stick lengths differ by brand: Fabuwood, KCD and US Cabinet Depot draw theirs at 96″; J&K's crown and quarter round come in 120″ lengths.

Every Piece at a Glance

Every run ends at a ceiling, a wall or a floor, none of them flat or level, and trim absorbs those errors. Here is the whole kit, with section sizes from Fabuwood's Allure spec book and prices from our Galaxy pages at the time of writing.

Prices are the displayed prices in the painted and stained Galaxy finishes we checked (Nickel, Dove, Cobblestone, Horizon), which match each other. The two oak finishes cost more on cabinets, so confirm oak trim on your quote. For the wider family (valances, pilasters, posts, legs and panels), see what millwork means in kitchen design, which prices the full Galaxy set.

Cabinet Crown Molding: Profiles, Sizes and Prices

Crown is the angled trim along the top of the wall cabinets. It is "sprung": it sits at an angle with a hollow behind it, which gives it a shadow line and makes it harder to cut than flat trim. Browse our crown molding collection by finish.

The profile families you'll see across brands:

• Cove crown: a single concave curve that suits shaker doors and most kitchens we quote.
• Classic (ogee) crown: the S-curve of traditional rooms.
• Shaker or flat crown: a square-edged band for shaker and slab doors.
• Stacked crown: crown on one or more flat strips, built up for a bigger gap.
• Dentil and rope: the tooth-block and twisted-cord accents of formal kitchens, usually layered under a crown. Among our lines, US Cabinet Depot's spec book lists a ¾″ rope moulding, for its Casselberry style only; Fabuwood's Allure book lists neither.

Fabuwood Allure Crown: Real Sizes and Prices

Fabuwood is the line we're asked about most. The Allure spec book (version 01.20.25) draws each profile at 96 inches with its section size, and our Galaxy pages show the prices. Size is height by projection as drawn; treat it as a planning figure and let the installer fit the top piece to the ceiling.

The number is a shape, not a grade; price follows the amount of wood. One catch: the spec book (page 65) says the CM-9 shaker crown is available only in Dove, Kona and Indigo, while our Galaxy Nickel pages list it too, so we confirm CM-9 in your finish before it goes on an order. The last column is simple arithmetic, the crown's drawn height plus the ¾″ starter it sits on; the installer scribes or rips the top piece for the last fraction of an inch.

Crown in Other Lines We Carry

From the spec books:

• KCD: Traditional Crown CM8 at 2¼″ × 2″, Royal Crown RCM8 at 3¼″ × 2¾″, Large Crown BCM8 at 3¼″ × 2⅝″, Cove Crown COM8 at 4¼″ × 2¾″, and Shaker Crown SCM8 at 3⅛″ × 2″ (Brooklyn White, Gray and Midnight only), all 96″ long.
• US Cabinet Depot: angled crowns at 1¾″ (ACM8) and 3″ (LACM8) tall, a cove at 3⅝″, and a 3″ decorative crown, all 96″.
• J&K: crowns from 2⅛″ (CM10) to 5¼″, plus "crown with base" pieces with the starter built in, all in 120-inch lengths.

A lumberyard crown or another brand's profile won't match your finish, so order crown from the same line, on the same order.

How the Crown Stack-Up Fills the Gap to the Ceiling

Crown is rarely a single piece. On a Fabuwood wall cabinet the build-up goes from the cabinet top upward: an optional MEX-8 extension band (6″) to gain height, the STRM-8 starter (2½″ × ¾″) laid on top to give the crown a nailing surface and push it forward, an optional STKM-8 stacking strip (2½″ × ⅝″) for an extra step, and the crown profile last. Add the pieces' heights and you know which combination fills your gap.

This is our planning guide, not a factory rule; the heights are the drawn sizes added together. A gap that falls between rows takes an STKM-8 stacking strip (another ⅝″) or a ripped extension. Ceilings are rarely level, so plan from the smallest measurement. How tall the uppers should be in the first place, and when a stacker cabinet beats a trim build-up, is its own decision, covered in kitchen cabinets to the ceiling with worked 8-, 9- and 10-foot layouts.

Flush or floating? Crown tight to the ceiling looks custom and leaves no dust shelf; crown that stops short forgives an out-of-level ceiling because there's no joint line to show the dip.

How Crown Attaches to the Cabinets

Crown is not nailed to the drywall or, on most modern cabinets, to the face frame. Fabuwood's Allure spec book says it plainly: its wall cabinets have full-overlay doors, and crown "should be installed using STRM-8 Starter Molding or similar molding bracing." Its arched wood hoods carry a similar note: "crown to be installed above cabinet, not on face frame." Frameless boxes have no face frame at all, so they always need a strip on top.

The install itself, as Family Handyman's cabinet crown guide describes it, runs like this:

1. Screw a nailing cleat or starter strip around the top perimeter of the cabinets (they use 1¼-inch screws), extending it about an inch past the cabinet face so the crown sits flush with the doors.
2. Cut the crown "upside down and backward" against the miter saw fence at half the corner angle, 45° for a square corner, with a stop block so the piece can't slip. Compound settings depend on the spring angle (commonly 38°, 45° or 52°).
3. Dry-fit, glue both miters, and fasten with 1¼-inch 18-gauge brad nails. Their guide nails into the cleat or face frame; on a full-overlay line like Fabuwood Allure, keep the fasteners in the starter strip, as the spec book asks.

From our job sites: pre-finish cut ends on stained trim so raw miters don't flash pale wood, and hire out the crown; toe kick, scribe and light rail are fair DIY jobs. For what the labor costs and how installers price trim, see our cabinet installation cost guide.

Light Rail Molding

Light rail is a slim strip fixed along the bottom edge of the wall cabinets. Its real job is screening under-cabinet LED strips and wiring from anyone seated at the table or island. Browse the light rail collection by finish.

Fabuwood's Galaxy light rail (LRM) is $149.50. The Allure spec book draws a separate LRM edge detail for each door family (Luna, Galaxy and Onyx share one; Nexus, Fusion and Imperio have their own), all on the same ¾″ × 1½″ section. Other spec books size theirs differently: KCD's LRM8 is 2¼″ tall by 1⅝″ deep, J&K's light rails are 1½″ × 2¼″, and US Cabinet Depot's angled rail is 1½″ × 2″, with a slimmer beveled rail at 1³⁄₁₆″ × 1⁹⁄₁₆″. Hold the fixture you plan to use against those numbers: the rail's drop has to be at least as tall as the LED channel it hides.

If lighting is in the plan, the rail goes on the original order, and its visual weight should match the crown. The wiring and fixture choices are in our under-cabinet lighting guide.

Toe Kick Height, Depth and Kick Plates

Every base cabinet stands on a recessed plinth so you can stand at the counter without stubbing the doors. The toe kick is the recess itself, and the kick plate (also toe kick skin, toe kick board or plinth) is the thin finished strip that covers its face.

Height and depth. Common guidance puts the standard toe kick at 3½″ tall (up to about 4″) and 3″ deep. Fabuwood builds its base and tall cabinets on a ¾″ × 4½″ unfinished plywood toe kick, and its 34½″ base height already includes it, so don't add the kick on top when you work out counter height. Accessible kitchens are the exception: the 2010 ADA Standards (section 306.2) count the space under an element from the floor up to 9 inches as toe clearance, and where a forward approach needs it, that clearance must reach at least 17 inches under the element, far deeper than any kick. So accessible designs leave the space open under the sink or a work surface rather than relying on a toe kick. Our ADA kitchen cabinet guide has the rest of those clearances, and the kitchen dimensions guide puts the kick in context.

What ships and what you order. That plywood kick arrives unfinished; the finished skin is ordered separately. In Galaxy, the TK8 is a 4½″ × ¼″ skin in moisture-resistant MDF (the spec book warns its green core shows on the cut edge) at $55.90 per 8-foot stick, and the newer TK8-3/4 is ¾″ plywood edgebanded on the bottom at $58.50. A solid-wood TKC cap ($7.80) finishes a kick that stops in the open next to a finished side, and a ¾″ toe kick clip (TKC-3/4, $10.40) is listed for the thicker kick. KCD's TKS8 skin is the same 4½″ × ¼″ at 96″. Plan one stick per base run and exposed island side, rounding up per run.

Special cases.

• Heater and vent grilles need a cut-out; mark them on the layout.
• Toe kick drawers replace the skin on that cabinet, so plan them per cabinet.
• Frameless cabinets on legs use a clip-on plinth that comes off for cleaning.
• Furniture-look islands. A furniture base or the BBM base board (5½″ × ¾″, $188.50 in Galaxy) replaces the plain kick.

Quarter Round vs. Shoe Molding at the Cabinet Base

A floor that dips mid-run leaves a dark gap under the straight toe kick, and a small molding closes it. The two options look similar and are not the same: quarter round is, as its definition says, a convex molding whose section is a quarter circle, so it's as deep as it is tall; base shoe is a quarter of an ellipse, taller than it is deep, so it sticks out less.

Our view: use the slimmer shoe where the kick is shallow or the floor is nearly flat, use quarter round where the gap varies more, and order either one in the cabinet finish so it reads as part of the base rather than the floor. On a room's baseboards, the trim usually follows the baseboard instead. Our end panels and fillers guide covers the rest of the floor-line kit.

Scribe, Corner and Other Small Trim

Scribe molding is the thin strip that covers the joint where a cabinet meets a wall that isn't flat. In Galaxy the simple SM8-S (¾″ × ¼″) is $39.00 and the decorative SM8-D (1¼″ × ⅜″) is $41.60, the cheapest insurance on the order. How to choose between caulk, scribe and a filler, and how installers scribe to a wall, is covered step by step in scribe molding for cabinets, explained; shop the scribe molding collection by finish.

• Outside corner molding (OCM8, $62.40) wraps an exposed vertical corner where a cabinet end meets a wall return or a peninsula turns. It's the piece most often left off a first order.
• Inside corner molding (ICM8, $59.80) is a small cove that covers the seam where two finished surfaces meet at 90 degrees.
• Fillers and skin panels aren't molding, but they go on the same order: a base filler (BF3, $26.00) closes a constant gap at a wall, and a skin finishes an exposed side. A quote with molding but no fillers or skins is often incomplete.

Matching Molding to Your Kitchen's Style

Shaker kitchens take a cove or small classic crown, plain light rail and square-edged trim. An ornate crown on a shaker box looks borrowed.

Modern slab kitchens want almost no visible molding: a flat crown or none, cabinets tight to the ceiling with a scribe strip, and the money spent on skins and panels instead.

Traditional kitchens use the full build-up: stacked crown, dentil or rope accents, base board molding on a furniture-style island. Budget two to three times the shaker trim spend.

Two-tone kitchens: trim follows the cabinets it touches, so crown in the wall-cabinet color, toe kick in the base color, island trim in the island finish. Flag each piece's finish on the order. Our two-tone color pairing guide covers the color side.

What Cabinet Molding Costs: A 10×10 Worked Example

Here is a standard 10×10 L-shaped kitchen priced in Galaxy: about 16 feet of wall cabinets (crown runs about 18 feet with the returns), 12 feet of those uppers getting under-cabinet lights, and base runs of 10 and 8 feet.

Add three sticks of quarter round ($187.20) if the floor is uneven. Crown and its starter are more than half the full-trim total, so the honest saving is a smaller crown or open tops, not skipping the light rail or scribe. For scale, Fabuwood's painted Galaxy 10×10 package (FGDV10 in Dove, for example) shows at $4,400, so full trim adds roughly 30% on top of the cabinets. A bigger L-shaped kitchen with an island comes to about $2,000 of trim in our millwork worked example, and the cabinet cost guide puts both in context.

How to Measure and Order

1. Measure each run, not the room. Crown and light rail follow the wall-cabinet runs (crown includes returns to the wall); toe kick follows the base runs plus exposed island sides.
2. Convert to sticks, rounding up per run. Divide by 96″ (or 120″ for J&K). A 110-inch run needs two sticks; put joins at corners, not mid-run.
3. Add a spare; every miter eats material, and a spare costs less than a second shipment.
4. Order trim with the cabinets. Stain and paint vary between production runs, and trim ordered months later can arrive a shade off.

Our cost estimator gives a ballpark; every quote we build includes the trim lines.

Common Molding Mistakes

• Choosing crown by photo instead of by gap. A 5½″ crown can't fit a 3″ gap.
• No starter strip. The crown gets ordered and the installer has nothing solid to nail it to.
• Light rail forgotten with LED lighting. The most common add-on order we process.
• No scribe in an older house. A caulk line along a wavy wall isn't a finish.
• Trim ordered after the cabinets, in a different finish batch.

Frequently Asked Questions

What are the different types of kitchen cabinet molding?

Crown molding at the top of the wall cabinets (with starter and extension strips under it), light rail under the uppers, toe kick skins on the base plinth, quarter round or shoe molding at the floor, and scribe and corner trim where cabinets meet walls. Fillers and skin panels are flat trim that go on the same order.

How do I choose the right size crown molding for my cabinets?

Measure from the top of the wall cabinets to the ceiling at both ends of each run and pick a crown no taller than the smallest gap, allowing ¾″ for the starter strip. In Fabuwood Galaxy that works out to CM-3 for about a 3″ gap (2⅞″ with the starter), CM-9 or CM-6 for about 4″, and CM-7 or CM-8 for about 5¼″–6¼″. Bigger gaps need the 6″ MEX-8 extension or a taller cabinet.

How much does crown molding for kitchen cabinets cost?

In Fabuwood's Galaxy finishes, crown is $117.00 to $367.25 per stick depending on profile, and the STRM-8 starter it fastens to adds $133.25 a stick. A 10×10 kitchen usually needs about three sticks of each: $819 for CM-4 crown plus starter, before installation.

Should kitchen cabinets go all the way to the ceiling?

Full height looks built in and removes the dust shelf, and at 8 feet it's often just a 39-inch upper and one crown (in Galaxy, 39-inch uppers have been dropped from most finishes, with Frost, Dove, Indigo and Timber keeping them; the rest use a 42-inch box). At 9 and 10 feet it takes stacked cabinets or a trim build-up. Our cabinets to the ceiling guide works through each height.

What is the standard toe kick height and depth?

The common standard is 3½″ tall and 3″ deep, though some lines run taller. Fabuwood uses a 4½″ kick, included in its 34½″ base height. Under the ADA, the space up to 9 inches off the floor counts as toe clearance, and accessible sinks and work surfaces leave it open.

Should I use quarter round or shoe molding on kitchen cabinets?

Either closes the gap between the toe kick and an uneven floor. Shoe molding (about ¾″ tall by ½″ deep) is slimmer and easier to clean around; quarter round (about ¾″ by ¾″) covers bigger dips. Order it in the cabinet finish so it reads as part of the base.

What is light rail molding used for?

It trims the bottom edge of the wall cabinets and hides under-cabinet light strips and wiring from view. Galaxy's LRM is a ¾″ × 1½″ section at $149.50; other lines we carry draw theirs from about 1³⁄₁₆″ to 2¼″ tall.

Does molding come with the cabinets, or can I use lumberyard trim?

Molding is sold separately, even with complete-kitchen packages, because every room's runs and ceilings differ. Lumberyard trim fits, but it rarely matches a factory finish, especially a stain. Order brand-matched trim with the cabinets.
