Buying a new refrigerator is a significant investment, and getting the measurements wrong can lead to costly returns or installation headaches. Our editorial team compared specifications, buyer feedback and key decision factors to create this step-by-step guide for measuring a 33-inch refrigerator. Whether you're replacing an old unit or fitting a new kitchen, accurate measurements ensure your refrigerator fits perfectly in the allotted space.

Why Accurate Measurement Matters

Refrigerators come in various sizes, and a 33-inch width is a common standard for many households. However, the actual dimensions can vary by brand and model. For example, some 33-inch models may be 32 7/8 inches wide while others are exactly 33 inches. Measuring the width, depth, height, and required clearance prevents issues like the refrigerator not fitting through doorways, blocking cabinets, or overheating due to poor ventilation. Proper measurement also helps you decide between counter-depth and standard depth models, which we cover later. Additionally, accurate measurements can save you from unexpected costs such as cabinet modifications or return shipping fees.

Tools You Will Need

• Measuring tape (at least 25 feet long for accuracy; a metal tape is preferred for rigidity)
• Notepad and pen (or a note app on your phone) to record all measurements
• Level (to check if floors are even; a 2-foot level works well)
• Step ladder (for measuring height to ceiling or upper cabinets safely)
• Flashlight (to see behind existing appliances and into dark corners)
• Pencil and masking tape (to mark measurements on walls or floors if needed)

Step-by-Step Measuring Guide

1. Measure the Width

1. Measure the width of the opening where the refrigerator will sit. Measure at the narrowest point, typically between countertops or cabinets. Take three measurements: at the top, middle, and bottom. Use the smallest measurement as your maximum width. For example, if the top is 33.2 inches, middle 33.1, and bottom 33.0, use 33.0 inches.
2. For the refrigerator itself, measure the width from side to side at the widest point, including hinges and handles. Most 33-inch refrigerators are about 32 7/8 to 33 inches wide. Leave at least 1/2 inch of clearance on each side (1 inch total) for easy installation and airflow. If your opening is exactly 33 inches, you may need to look for a model that is slightly narrower.

2. Measure the Depth

1. Measure the depth of the space from the back wall to the front edge of the counter or cabinets. Include any baseboard or trim that may reduce usable depth. For instance, if the counter overhangs by 1 inch, measure from the wall to the front of the counter, not the cabinet face.
2. Measure the refrigerator depth from the back to the front, including handles and doors. Standard depth refrigerators are 30-36 inches deep, while counter-depth models are 24-30 inches. For a flush look, choose counter-depth, but note that interior capacity is smaller. For example, a counter-depth model may offer 20 cubic feet versus 25 cubic feet for standard depth.
3. Add at least 1 inch of clearance behind the refrigerator for ventilation. If the refrigerator has rear coils, you may need 2-3 inches. Check the manual. Also, consider that some models require side clearance for airflow; typically 1/8 inch on each side is sufficient, but check specifications.

3. Measure the Height

1. Measure the height of the opening from the floor to the bottom of the upper cabinet or ceiling. Measure at the front and back, as floors may be uneven. For example, if the front height is 70 inches and the back is 69.5 inches, use the smaller measurement as your maximum height.
2. Measure the refrigerator height from the floor to the top hinge or highest point. Some models have adjustable leveling legs that add height. Leave at least 1/2 inch clearance above for airflow and to allow the refrigerator to be tilted during installation. If the refrigerator has a top hinge that protrudes, include that in your measurement.

4. Check Door and Path Clearances

1. Measure doorways, hallways, and stairwells the refrigerator must pass through. Remove doors and handles if necessary. Standard interior doors are 30-32 inches wide, so a 33-inch refrigerator may require tilting or removal of trim. Measure the height as well to ensure the refrigerator can be tilted without hitting the ceiling.
2. Ensure the refrigerator doors can open fully in its final location. Allow space for the doors to swing without hitting walls or cabinets. French door models need less clearance than side-by-side models. For example, a French door refrigerator may require only 1 inch of side clearance, while a side-by-side may need 2 inches on the hinge side.

Counter-Depth vs Standard Depth

Counter-depth refrigerators are designed to align with standard countertops (typically 24-25 inches deep). They offer a built-in look but have less interior space. Standard depth refrigerators stick out 6-8 inches beyond counters, providing more storage. For a 33-inch wide space, counter-depth models are popular for seamless kitchen designs. However, if you need maximum capacity, standard depth is the better choice. Measure your counter depth and compare to the refrigerator's depth including handles to decide. For instance, if your counter is 25 inches deep, a counter-depth refrigerator at 28 inches deep will still protrude slightly, but less than a standard depth model at 34 inches.

Common Mistakes to Avoid

• Forgetting to measure the height of doorways and hallways: Many people only measure the kitchen opening, but the refrigerator must travel through your home. Always measure the path from the delivery truck to the final location.
• Not accounting for handles and hinges: Refrigerator width and depth specifications often exclude handles. Always include them in your measurements, as they can add 1-3 inches.
• Ignoring ventilation requirements: Insufficient clearance can cause the compressor to overheat and fail prematurely. Follow manufacturer recommendations for rear, side, and top clearances.
• Assuming all 33-inch models are the same size: Different brands have different tolerances. Always check the exact dimensions of the specific model you are considering.

Final Tips for a Perfect Fit

• Always measure twice and write down all dimensions.
• Check the manufacturer's specifications for exact dimensions and clearance requirements.
• Consider the refrigerator's water line and electrical outlet location. Ensure they are accessible and within reach of the unit's connections.
• If installing in a tight space, remove the refrigerator doors and hinges for easier maneuvering. Most models have reversible doors that can be removed with basic tools.
• Use a level to ensure the floor is even; adjust leveling legs as needed to prevent wobbling and ensure proper door alignment.
• Take photos of the space and measurements for reference when shopping.
