How to Measure for a New Kitchen Faucet

Step 1: Identify Your Mounting Type

Start by determining whether your faucet is deck-mounted or wall-mounted. Deck-mounted faucets install directly into the sink or countertop, while wall-mounted faucets connect to plumbing inside the wall above the sink. Your replacement faucet must match your existing installation style unless you plan to modify plumbing. Not sure which type you have? Our Types of Kitchen Faucets guide breaks down the key differences.

Step 2: Count the Mounting Holes

Next, count how many mounting holes are in your sink or countertop. Most kitchen faucets require between one and four holes, depending on whether they include accessories like a side sprayer or soap dispenser. If your current faucet has a deck plate, it may be covering unused holes – check underneath the sink for a clearer view. Choosing a faucet that matches your hole count will ensure proper installation and prevent exposed openings.

Step 3: Measure Faucet Hole Spacing & Diameter

If your sink has multiple mounting holes, measure from the center of the far-left hole to the center of the far-right hole. This center-to-center measurement determines whether a deck plate will fully cover the openings. Then, measure the diameter of each hole to ensure your new faucet will fit securely.

Step 4: Measure the Deck Thickness

Measure the thickness of your sink or countertop deck, the surface where the faucet installs. Faucets are designed to accommodate a specific maximum deck thickness, and exceeding it may prevent proper tightening or stability. Be sure to include any additional layers, like tile or mounting surfaces, in your measurement.

Step 5: Measure Faucet Height, Reach & Surrounding Clearance

Use the diagram at the start of this section to measure your current faucet’s overall height, spout height, and spout reach. Then, evaluate the surrounding space to ensure your new faucet won’t interfere with walls, backsplashes, cabinets, or windows. Measure from the center mounting hole back to the wall for depth clearance, and upward to any obstruction for maximum height. For comfortable everyday use, measure from the mounting hole to the center of the sink basin to determine ideal spout reach.

Step 6: Choose a Faucet That Fits

Now that you’ve confirmed your mounting type and key measurements, you’re ready to pick out the perfect faucet for your kitchen. Double-check hole compatibility, deck thickness, and clearance before making a selection. Taking a few extra moments to verify these details will help ensure a smooth installation and the right fit.
