What are the standard sizes for kitchen faucets?

Kitchen faucets come in various sizes, but there are a few standard measurements that are commonly used. The most common standard sizes for kitchen faucets include:
Centerset Faucets: Centerset faucets are designed to fit sinks with three pre-drilled holes that are 4 inches apart from center to center. The standard centerset faucet has a spout and two handles, typically one for hot water and one for cold water.
Single-Hole Faucets: Single-hole faucets require only one hole for installation. They have a single handle for controlling both the water temperature and flow. The standard size for a single-hole kitchen faucet is typically around 1.375 inches (35 mm) in diameter.
Widespread Faucets: Widespread faucets consist of separate components, including a spout and two handles, which are installed into three separate holes in the sink or countertop. The distance between the handles can vary, but a common standard is 8 inches.
Pull-Down/Pull-Out Faucets: Pull-down and pull-out faucets feature a spray wand that can be pulled down or out of the faucet body for easy maneuverability and rinsing. These faucets typically have a larger height to accommodate the retractable spray head.
It's important to note that while these sizes are common, variations and different sizes may exist depending on the specific manufacturer and model. Additionally, it's advisable to measure the existing holes in your sink or countertop and check the product specifications of the faucet you are considering to ensure a proper fit.
When choosing a kitchen faucet, consider not only the size but also other factors such as the style, finish, features (e.g., spray options, water-saving features), and overall functionality that meet your needs and preferences.
