The standard faucet hole sizes for kitchens and bathrooms are 1 3/8″ (1.375 Inches or 34.925 mm) in diameter unless otherwise mentioned in the specification. However, faucet holes may vary in size depending on the particular make and model.
Then, how do I know what size faucet I need?
Measure the distance between the handles. Hold the the tape measure above the faucet if it’s in the way. If the distance is six inches or more you need a “widespread” or “eight inch spread” faucet.
Beside this, what is the standard sink faucet size?
1 3/8 inches
Similarly one may ask, why are kitchen faucets so tall?
Convenience and functionality are two of the main reasons to choose a high-arc faucet for a kitchen, but they also contribute to the overall look of the kitchen in that they’re quite obvious compared to low-arc faucets.
