How to Plan Your Garage Storage: A Step-by-Step Measurement Guide

The number one reason garage cabinet installations go wrong isn’t bad products — it’s bad measurements. A cabinet that blocks the garage door track, a worktop that prevents the car door from opening, or wall cabinets mounted over an electrical panel all trace back to the same root cause: someone skipped the planning step.

This guide walks you through the complete measurement and planning process for garage cabinet installation. Whether you’re outfitting a 1-car garage with a single wall of cabinets or a 3-car garage with a full workshop setup, these steps ensure your investment fits perfectly the first time.

Step 1: Measure the Garage Footprint

Start with the basic dimensions of your garage. You need three measurements for each wall where you’re considering cabinets.

Wall width. Measure from corner to corner at floor level. Do this for every wall you might use. Common garage widths: 1-car (10–12 feet), 2-car (18–20 feet), 3-car (28–32 feet). The back wall and one or both side walls are your primary installation surfaces.

Wall height. Measure from floor to ceiling. Standard garage ceiling height is 8–10 feet. If you have a garage door opener mounted to the ceiling, also measure from the floor to the bottom of the opener rail — this is your maximum height for anything on the back wall along the center line.

Wall depth available. This is the distance from the wall to the first obstruction (parked car, garage door when open, etc.). Standard cabinet depth is 24 inches. You need at least 24 inches of clear depth plus any desired working space in front of the cabinets.

Step 2: Map Every Obstruction

This is the step most people skip — and the one that causes the most expensive mistakes. Walk each wall with a tape measure and note the exact position of every obstruction.

Electrical panel. Note the location, width, height, and required clearance. The National Electrical Code requires 36 inches of clearance in front of the panel and 30 inches of width. You cannot mount cabinets within this zone. Mark it on your sketch as a no-install area.

Water heater. If your water heater is in the garage, measure its footprint and clearance requirements. Most codes require 12–18 inches of clearance around gas water heaters. This area is off-limits for cabinet installation.

Garage door tracks. The vertical tracks on both sides of the garage door take up 3–4 inches of wall space. The horizontal tracks extend along the ceiling for 8–12 feet from the door. Cabinets on side walls must be positioned behind the end of the horizontal track to avoid interference with the door mechanism.

Light switches, outlets, and light fixtures. Mark every switch, outlet, and ceiling light. Cabinets can be installed around outlets if you plan access holes, but switches must remain accessible. Consider adding outlets inside base cabinets for tool chargers — an electrician can add one in about 30 minutes.

Hose bibs and utility connections. Gas lines, water supply, and exterior hose bibs that penetrate the garage wall need clearance. Measure their exact position — they’re easy to forget until the cabinet is on the wall.

Windows. Measure window position, width, and height. Wall cabinets mounted on either side of a window can frame it nicely, but you need to plan for the light and access you want to maintain.

Step 3: Measure Vehicle Clearance

If you park in the garage, your car dictates where cabinets can go. These measurements are non-negotiable.

Car length. Park your car in its normal position and measure from the back wall to the front bumper. This tells you how much back-wall depth is behind the car for base cabinets. Most sedans leave 3–4 feet behind them; SUVs and trucks leave 1–2 feet or none.

Door swing radius. Open both front doors fully. Measure from the car body to the widest point of the open door. Add 6 inches for comfortable clearance. This is the minimum distance from the car to any cabinet on the side wall. Typically 42–48 inches from the car’s side to the nearest cabinet.

Hood height. Measure from the floor to the top of the car’s hood or roof. Wall cabinets on side walls should be mounted above this height (plus 6 inches of clearance) to avoid any risk of contact when parking.

Mirror width. Measure the total width of your car including side mirrors. Subtract this from the garage interior width to find your available side clearance. Split this between both sides, with at least 36 inches on the driver’s side for comfortable entry/exit.

Step 4: Create Your Floor Plan

You don’t need CAD software. Graph paper works. Use a scale of 1 square = 6 inches.

Draw the garage outline. Mark every obstruction from Step 2 with its exact position and clearance zone. Draw your car’s parked footprint (including door swing zones). The remaining clear space is your installation area.

Now sketch cabinet placements within the clear zones. Standard KLOVO cabinet widths are 24 inches and 36 inches. Base cabinets are 24 inches deep and 36 inches tall. Wall cabinets are 24 inches deep and 30 inches tall. Worktops span between base cabinets and add a functional surface.

Pro tip: Leave 2 inches of clearance on each side of a cabinet run for installation tolerance. Walls are rarely perfectly plumb or square, and that extra inch on each side prevents headaches during mounting.

Step 5: Plan Your Mounting Heights

Cabinet mounting height affects both usability and aesthetics. Here are the standard guidelines:

Base cabinets: Sit on the floor (or on optional leg levelers if your garage floor slopes). Top surface at 36 inches — standard countertop height, same as a kitchen.

Wall cabinets above base cabinets: Bottom of wall cabinet at 54 inches from the floor (18-inch gap above base cabinet top). This creates an 18-inch backsplash zone perfect for a worktop, power strip, or tool pegboard.

Wall cabinets without base cabinets below: Bottom at 48–60 inches from the floor, depending on your height and what’s stored below. Higher mounting leaves more floor space for tall items (ladders, bicycles, trash cans).

Wall cabinets above car-hood height: Bottom at 60–72 inches. Only practical on side walls where the car parks alongside. Contents should be items you access less frequently since they require a step stool.

Step 6: Check Your Wall Structure

Garage cabinets must be mounted into wall studs — drywall anchors alone cannot support the weight. Use a stud finder to locate and mark every stud in your installation zone.

Standard stud spacing is 16 inches on center. Some garages (especially in attached garages built after 2000) use 24-inch spacing. Mark studs with painter’s tape so you can see the mounting points when you’re ready to install.

For concrete or cinder block walls (common in detached garages), you’ll need concrete anchors rated for the total weight of the loaded cabinet. A fully loaded KLOVO wall cabinet can weigh up to 550 lbs (50 lb cabinet + 500 lb capacity load). Use 3/8-inch concrete wedge anchors minimum.

Step 7: Calculate Your Configuration

With your floor plan and mounting heights established, you can now determine exactly which cabinets and accessories you need.

Count your linear feet. Add up the total width of available installation space on each wall. A 12-foot back wall with a 36-inch electrical panel clearance gives you 8.5 usable feet. An 8-foot side wall behind the car gives 8 usable feet.

Choose your mix. 36-inch cabinets are the most space-efficient (more storage per dollar). 24-inch cabinets fit into gaps and corners where 36-inch won’t. Mix sizes to fill your available width with minimal wasted space.

Add worktops. Any run of two or more base cabinets benefits from a worktop. Standard worktop configurations span between two base cabinets, creating a 24-inch to 48-inch work surface at counter height.

Common Measurement Mistakes to Avoid

Forgetting the garage door when open. Many homeowners measure with the door closed. When the garage door opens, it retracts along the ceiling and extends 8–12 feet from the door opening. Tall cabinets or overhead storage can interfere with the retracted door.

Ignoring floor slope. Garage floors are sloped toward the door for drainage — typically 1/8 inch per foot. Over an 8-foot cabinet run, that’s 1 inch of slope. Base cabinets need adjustable leveling feet (included with KLOVO base cabinets) to compensate.

Measuring to the drywall, not the stud. Your cabinet mounting point is the stud face, which is 1/2 inch behind the drywall surface. This matters when planning tight clearances near obstructions.

Not accounting for cabinet door swing. A 36-inch cabinet with a single door needs 18 inches of clearance in front to open fully. Double-door cabinets need less (each door is only 18 inches wide). If your car parks close to a wall, double-door cabinets or wall-mount-only configurations prevent door-on-door conflicts.

Frequently Asked Questions

How do I measure my garage for cabinets?

Measure wall width, ceiling height, and depth from wall to the nearest obstruction on every potential installation wall. Then map all obstructions (electrical panel, water heater, garage door tracks, outlets). Finally, measure your parked car’s footprint including door swing radius. The remaining clear space is your installation area.

How much space do I need between garage cabinets and my car?

Allow at least 36 inches between the car body and any cabinet on the driver’s side for comfortable door clearance. On the passenger side, 24 inches is workable if you don’t need regular access. For wall cabinets mounted above the car, maintain 6 inches above the car roof or hood height.

What height should garage wall cabinets be mounted?

When mounted above base cabinets, wall cabinets go at 54 inches from the floor (18-inch gap above the countertop). When mounted alone, 48–60 inches from the floor is standard. On side walls near a parked car, mount at 60–72 inches to clear the vehicle.

Can I install garage cabinets on a concrete wall?

Yes. Use 3/8-inch concrete wedge anchors rated for the total weight of the loaded cabinet (up to 350 lbs for a fully loaded KLOVO wall cabinet). Pre-drill holes with a hammer drill and masonry bit. Concrete walls are actually excellent mounting surfaces because anchor placement is unrestricted — you’re not limited to stud locations.
