what size is a garden hose fitting

A standard garden hose fitting is usually 3/4 inch garden hose thread (GHT) , and it connects to hoses that are typically 1/2", 5/8", or 3/4" in inside diameter.

What Size Is a Garden Hose Fitting?

Garden hose sizing is confusing because there are two things going on at once:

  • The hose size (inside diameter of the hose)
  • The fitting/thread size (the metal or plastic end that screws onto the faucet or nozzle)

Most of the time, when people ask “what size is a garden hose fitting,” they mean the threaded connector at the end.

The Most Common Garden Hose Fitting Size

  • The most common fitting size on typical US garden hoses is 3/4 inch GHT (Garden Hose Thread).
  • This is the size on:
    • Most outdoor spigots (hose bibs)
    • Most standard hoses
    • Most spray nozzles and sprinklers

Even if the hose is 5/8" or 1/2" inside diameter, the threaded fitting on the end is still usually 3/4" GHT.

Common Hose vs Fitting Sizes (Quick View)

Here’s a simple way to think about it:

[1][9][3][5] [9][5][7]
What you’re measuring Typical sizes What it means
Hose inner diameter 1/2", 5/8", 3/4" Flow size; 5/8" is the most common home-garden hose size.
Threaded fitting size 3/4" GHT (most common) Standard thread that screws onto outdoor faucets, sprinklers, etc.

How to Tell What Size You Have

If you’re at home trying to match parts:

  1. Check the hose diameter (for flow):
    • Look printed on the hose jacket: it often says 1/2" , 5/8" , or 3/4".
  1. Check the fitting/thread (for compatibility):
    • Almost all residential garden gear (spigots, hose ends, sprinklers) is 3/4" GHT , so new accessories marked “standard garden hose” will typically fit.
  1. If in doubt:
    • Take the old fitting or hose end to the store and physically match it, or look specifically for “3/4 inch GHT” on the packaging.

Mini Example Story

Imagine you buy a new sprinkler and it says “fits standard 3/4 in. garden hose.” You have a slim, lightweight hose labeled 1/2". You might worry it won’t fit. The good news : the hose is 1/2" inside, but the fittings on the ends are almost certainly 3/4" GHT , so the sprinkler will screw on just fine.

In short: your garden hose fitting is almost always 3/4" GHT, and the hose itself is usually 5/8" for typical home use.

TL;DR:

  • Standard garden hose fitting: 3/4 inch GHT
  • Common hose sizes: 1/2", 5/8" (most common), 3/4" inside diameter
