What Size Faucet for a Kitchen Sink: How to Measure

Your kitchen faucet is a focal point, so invest the time to get the sizing right.

Whether you are redesigning your entire kitchen or simply choosing a new faucet for maximum impact, getting the size right is crucial. But how do you choose the correct faucet with so many styles, models, and features available?

We show you what size faucet you need for a kitchen sink and explain how to work out the size ratios.

Key Takeaways

  • Consider height, depth, and reach of your faucet to ensure it fits over the sink and has enough clearance for washing dishes.
  • Choose between high-arc or low-arc faucets depending on your preference and if you have cabinets over the sink.
  • Industry-standard faucet sizes usually extend over a sink by 6 to 8 inches, with high-spout faucets having a height of 10 inches.
  • When measuring your faucet, measure the height from the base to the top of the spout curve, the depth from the spout end to the faucet’s stem, and the spout height to the base of the faucet.

What Size Faucet for a Kitchen Sink?

Why does size matter? Well, for one thing, if the faucet is too small, you will have water splashing all over your countertop. The spout needs to overhang the sink with enough clearance to reach at least halfway into the sink.

Secondly, the height is critical because it could impede how the tap moves from side to side. Third, the location of the handles is vital because you will need to operate the faucet without scraping your knuckles on the worktop.

Here’s what you need to consider:


Measure from the tallest point of the faucet to the base. Ensure that the tape measure is straight.

Spout Height

The spout height determines the clearance you have when washing larger dishes.


You can buy high-arc and low-arc faucets, and the size of the arc determines the spout curve above the sink. High-arc faucets make a statement and are better for washing larger items. However, they can obstruct the view when placed in front of a window.

Low-arc faucets are less conspicuous but better in locations where a lower profile is advantageous. If your kitchen sink is under a cabinet, you may need a lower tap to get the movement you need.


The reach of your new faucet is crucial if you want to wash larger dishes. If the tap is set too far back on the worktop, it will splash water. The reach of your tap also determines how far you lean over to wash up.

No one wants to strain their back while doing the dishes! One simple solution to this problem is to choose a faucet with a pull-out spout. Your reach is extended, and you can direct the water where you want.

Top Tip

The minimum your faucet should reach is your drain hole to ensure water flows freely down the drain.

Faucet to Sink Ratio

So, what is the ideal faucet to sink ratio? Get the measurements wrong, and your tap will lack the depth needed to reach above the sink. If the faucet is too tall, it will obstruct the view out of the window.

There is no template or kitchen faucet size chart that gives you all the dimensions you need. However, there are industry-standard sizes to help you. Most faucets extend over a sink by six to eight inches. This gives you enough clearance to wash hands and dishes without leaning over too far.

Here’s a more detailed look at faucet size ratios:

  • High-spout faucets generally have a height of 10 inches.
  • Medium spouts have a reach of six to eight inches.
  • Low-spout faucets have a reach of four to six inches.

How to Measure a Kitchen Faucet Size

Before racing off to the hardware store to buy your new kitchen faucet, you’ll need to know how to measure your tap for the correct size. The above diagram should make it a bit easier to understand.

What You’ll Need

  • Measuring tape or ruler.
  • Pencil and notepad.
  • Measure the height of the faucet from the base to the top of the spout curve. Make a note on your notepad.
  • Measure the depth of the tap from the spout end to the faucet’s stem. This tells you how deep the tap will reach.
  • Measure the spout height to the base of the faucet.

Tips for Choosing a Kitchen Sink

We all need help sometimes, and it’s no different when choosing a new kitchen faucet. We share a few tips to get you started that will hopefully make life easier.

Choose the Right Material

While we can focus on the faucet’s size, we also need to consider what it’s made from. It needs to match the sink and possibly other kitchen appliances. A black tap will clash with a chrome sink and vice versa.

The most common materials are chrome and stainless steel. They fit most decor schemes and look modern. Other materials like nickel are coming back into style but can suffer the ravages of rust and water damage more easily.

Choose the Right Style

Faucets come in several styles and designs, which is great for choice but not when you have to make a decision. Start by selecting a faucet that matches your taste and existing fittings. A modern tap will look at odds with a victorian-style kitchen or bathroom.

Choose Added Features

Kitchen and bathroom faucets come with lots of additional benefits like touchless control, adjustable spray, and extendable spouts. Obviously, the cost is a factor because the more advanced the tap, the bigger the price tag.

However, if you have the funds, selecting a tap full of the latest gadgets could make your washing regime much more convenient.

It’s worth noting that the more you spend, the better quality you get. The faucet valve is more robust and lasts longer, and the material stands up to the punishment of your kitchen.


Can a Faucet be Too Big for a Sink?

It is unlikely that your faucet is too large for your sink, but it may not fit your design brief and be too big in that sense. Some commercial faucets with industrial-style pull-out spouts can seem a little too big aesthetically, but they should still fit your sink.

Does Your Faucet Need to Match Your Sink?

Most people would like their faucet to match their sink and overall design scheme, but it all comes down to taste. Your faucet can be any shape, size, or design you want as long as it functions as it should and doesn’t dribble water over your countertop.

Final Thoughts

Getting the size of your new kitchen faucet right takes a bit of planning and accurate measurements. You need to work out the height, depth, and reach to ensure it hangs over the sink and fits into its surroundings.

So, when the time comes to swap your faucet, grab your tape measure and get to work.
