How To Measure Your Closet Space
Accurate measurements are the foundation of a perfect custom closet. This guide walks you
through each step of measuring your space—whether it’s a walk-in or reach-in closet—to ensure
your new Hi-Tech Closets system fits perfectly. Take your time and measure carefully to the
nearest 1/8″ (or even 1/16″). A friend’s help can make the process easier and more precise.
Tools & Preparation
• Tape Measure (25 ft) – Your main tool for all measurements. Tip: A laser distance
measurer is helpful for long spans but not required.
• Pen/Pencil & Notepad – Sketch your closet layout and label each wall or section.
• Step Stool or Ladder – For safely measuring ceiling heights or upper areas.
• Measuring Partner (Optional) – Keeps the tape straight for accuracy.
• Angle Finder (Optional) – Useful for sloped ceilings.
• Level or Carpenter’s Square (Optional) – To check if walls are plumb or corners are
square.
• Preparation Tip: Remove any items blocking the walls, corners, or floor.
Step 1: Measure Wall Widths
• Measure each wall in three spots—near the floor, at mid-height, and near the ceiling.
• Take floor-level measurements just above the baseboard, not over it.
• Label and note all points (e.g., ‘Wall A: bottom 120″, middle 119¾″, top 119½″).
• Use the smallest measurement for design accuracy.
• Repeat for every wall including side and return walls.
Step 2: Measure Closet Depth
• For reach-in closets, measure both sidewalls (return walls) from the back wall to the inside
edge of the door trim.
• For walk-in closets, measure the distance between opposing walls or potential island areas
to check available walkway space.
• If measuring above baseboards, note any small differences at floor level.
• Start at the 1″ mark of your tape and subtract 1″ from the reading for more accuracy.
Step 3: Measure Ceiling Height
• Measure height from floor to ceiling in multiple locations.
• Use the lowest height for design reference.
• Identify soffits, drops, or bulkheads and record their size and position.
• For sloped ceilings, measure both the highest and lowest points and note where the slope
begins and ends.
Step 4: Measure Doors and Openings
• Measure door width from frame to frame including trim.
• Measure door height from floor to top of frame.
• If there’s space above the door, record the header height.
• Note the door type and swing direction.
• Record any obstructions like hinges or tracks.
Step 5: Locate Obstacles & Features
• Identify outlets, switches, lights, vents, and windows. Record their location and
dimensions.
• Note baseboard heaters, radiators, or other projections that affect design.
• Mark pipes, access panels, or columns on your sketch.
• Include built-in items like safes or attic hatches.
• Keep airflow unobstructed around any vents.
Step 6: Double-Check & Finalize Measurements
• Re-measure key dimensions for accuracy.
• Cross-check that opposite walls align and numbers add up correctly.
• Record precise figures (to 1/8″ or 1/16″) and round down slightly if unsure.
• Organize your notes clearly—create a diagram or measurement table.
• Take photos of complex areas for your designer.
