2. Before You Start Measuring
Proper preparation ensures accurate measurements and saves time.
Preparation Checklist
Clear the Kitchen
Remove furniture, appliances, and any obstacles that might interfere with measuring.
Check Wall Construction
Identify load-bearing walls, electrical outlets, plumbing connections, and HVAC vents.
Document Current Layout
Take photos from multiple angles to reference later during planning.
Plan Your Approach
Work systematically around the room, measuring one wall at a time.
Important Considerations
Electrical & Plumbing
Note locations of outlets, switches, gas lines, and water supply lines that may affect cabinet placement.
Structural Elements
Mark any support beams, posts, or load-bearing elements that cannot be moved.
Future Changes
Consider planned electrical or plumbing modifications before finalizing measurements.
Building Codes
Check local requirements for clearances around appliances and work surfaces.
3. Step-by-Step Measuring Guide
Follow these detailed steps for professional-quality measurements.
Measure Wall Lengths
Measuring Technique
- Start at one corner and measure to the next corner
- Measure at three heights: floor, middle (36"), and ceiling
- Record the shortest measurement (walls are rarely perfectly straight)
- Measure to the nearest 1/8 inch for accuracy
Pro Tips
- • Use a second person to hold the tape for long measurements
- • Double-check all measurements before recording
- • Mark the wall lightly with pencil to verify tape placement
- • Measure from the same reference points consistently
Measure Heights and Depths
Ceiling Height
- • Measure from floor to ceiling in multiple locations
- • Check for soffits or dropped ceilings
- • Note any slopes or irregularities
- • Standard: 8-9 feet for most homes
Window & Door Heights
- • Measure from floor to bottom of window/door
- • Measure the height of the opening
- • Measure from top to ceiling
- • Include trim in measurements
Wall Depth/Projection
- • Check for any wall irregularities
- • Measure around pipes or ducts
- • Note electrical boxes depth
- • Standard wall depth: 4-6 inches
Mark Obstacles and Features
What to Measure & Mark
Distance from corners, height from floor
Water supply, drain lines, shut-off valves
Stove, oven, range hood connections
Floor, wall, and ceiling vents
Measuring Obstacles
- 1. Measure distance from nearest corner to center of obstacle
- 2. Measure width/diameter of the obstacle
- 3. Measure height from floor (if wall-mounted)
- 4. Note any required clearances per building codes
- 5. Take photos for reference during planning
Check for Square and Level
3-4-5 Triangle Method
Use this method to check if corners are square:
- 1. Measure 3 feet along one wall from the corner
- 2. Measure 4 feet along the adjacent wall
- 3. Measure the diagonal between these two points
- 4. If the diagonal is exactly 5 feet, the corner is square
Level Checking
4. Creating Your Floor Plan
Transform your measurements into an accurate, detailed floor plan.
Drawing Your Plan
Choose Your Scale
Use a consistent scale throughout your drawing:
- • 1/4" = 1' (most common for kitchen plans)
- • 1/2" = 1' (for detailed areas)
- • 1" = 1' (for very detailed work)
Step-by-Step Drawing
- 1. Start with the room outline using your wall measurements
- 2. Add doors and windows with their exact sizes and locations
- 3. Mark all electrical outlets, switches, and fixtures
- 4. Add plumbing connections and gas lines
- 5. Include HVAC vents and any structural elements
- 6. Note ceiling height and any soffits
- 7. Label all measurements clearly

Learn from these frequent errors to ensure perfect measurements every time.
Forgetting to Account for Trim
Not including baseboard, crown molding, or window trim in measurements.
Solution: Always measure to the finished surface, including all trim work.
Measuring Only at One Height
Walls are rarely perfectly straight - measuring only at one height can lead to errors.
Solution: Measure at floor, middle, and ceiling height, use the shortest measurement.
Not Checking for Square
Assuming corners are square without verification can cause major fitting problems.
Solution: Use the 3-4-5 triangle method to check every corner.
Ignoring Electrical and Plumbing
Not marking utility locations can lead to costly modifications later.
Solution: Document all outlets, switches, and plumbing connections precisely.
Rounding Measurements
Rounding to the nearest inch instead of measuring to 1/8" accuracy.
Solution: Always measure and record to the nearest 1/8 inch for precision.
Poor Documentation
Not clearly labeling measurements or creating unclear diagrams.
Solution: Use clear labels, take photos, and create detailed notes.
Measuring Alone
Trying to measure long distances without assistance leads to inaccuracy.
Solution: Use a helper for measurements over 8 feet or use a laser measure.
Not Double-Checking
Relying on a single measurement without verification.
Solution: Always measure twice and verify critical dimensions.
7. Professional Measuring Tips
Expert techniques used by kitchen designers and contractors.
Measurement Techniques
Use Running Dimensions

8. Frequently Asked Questions
Common questions about measuring for kitchen cabinets.
How accurate do my measurements need to be?
Professional cabinet measurements should be accurate to within 1/8 inch. This ensures proper fit and minimal adjustments during installation.
Should I measure before or after removing old cabinets?
Measure after removing old cabinets to get accurate wall and floor measurements. Old cabinets can hide irregularities and utility locations.
What if my walls aren't square?
Most walls aren't perfectly square. Note the degree of variation and plan for filler strips or custom sizing to accommodate irregularities.
How do I measure for a kitchen island?
Measure the desired location, ensuring 36" minimum walkway clearance on all sides. Mark electrical and plumbing locations for the island.
Can I measure a kitchen by myself?
While possible, it's much easier and more accurate with a helper. For solo measuring, use a laser measure or secure the tape end firmly.
What's the difference between rough and finish measurements?
Rough measurements are to the framing. Finish measurements include drywall, flooring, and trim. Always use finish measurements for cabinets.
How do I account for appliances in my measurements?
Measure the actual appliance dimensions plus required clearances. Don't rely on standard sizes - measure your specific appliances.
Should I hire a professional to measure?
Many cabinet companies provide free measuring services. This can be worth it for complex layouts or if you're unsure about your measurements.
How long should measuring take?
Plan 1-2 hours for a typical kitchen. Complex layouts with many obstacles may take longer. Don't rush - accuracy is more important than speed.
What if I make a mistake in my measurements?
Small errors can often be corrected with filler strips. Major errors may require reordering cabinets. Always double-check critical measurements.
