Watering and hoses
What is the standard garden hose size?
There are three size numbers on a hose package: the diameter of the hose, its length, and the thread on its fittings. For most US homes, a 5/8 inch hose is the everyday standard, and the fittings are 3/4 inch garden hose thread.

Diameter
Hose diameter means the inside diameter, the width of the channel the water flows through. Common sizes are:
- 1/2 inch: light and easy to coil; fine for short runs, pots and balconies.
- 5/8 inch: the most common size for home gardens; a good balance of flow and weight.
- 3/4 inch: carries the most water; heavier, used for long runs and big sprinklers.
Compare them in 5/8 vs 1/2 inch and 3/4 vs 5/8 inch. To check a hose you already own, see how to measure hose diameter.
Length
Hoses are usually sold in 25, 50, 75 and 100 foot lengths. Buy the shortest length that reaches the far corner of your garden. A longer hose is heavier, costs more and delivers less water at the end, because water loses pressure as it travels through more hose.
Measure from your faucet to the farthest spot you need to water, following the path the hose will really take around beds and corners.
Thread
Whatever the diameter, most US hoses end in 3/4 inch garden hose thread (GHT), so they fit standard faucets, nozzles and sprinklers. See garden hose thread size.

Frequently asked questions
What is the most common garden hose size?
For US homes, 5/8 inch inside diameter is the most common, usually in 50 foot lengths, with 3/4 inch garden hose thread fittings.
Is a garden hose 1/2 or 3/4?
Both exist. The hose itself may be 1/2, 5/8 or 3/4 inch inside diameter, while the fittings on almost all US hoses are 3/4 inch garden hose thread.
Does hose length affect water pressure?
Yes. Water loses pressure as it moves through a hose, so a longer hose delivers less flow at the end than a short one of the same diameter.
