When choosing a garden hose, the right diameter is one of the most important criteria. This article gives you an overview of the garden hose diameters that you can use for private use.
In a nutshell
- Garden hoses are selected by inner diameter
- Inside diameter is given in inches or mm
- ranges from 6 to 50 mm
- Diameter must correspond to the outside diameter of the fittings
Garden hose: standard diameter
When you are looking for garden hoses, there are certain standard sizes that you will come across the most. These are the three sizes you will encounter most often:
- 1/2 inch: 12.7 mm (DN 12)
- 5/8 inch: 15.9 mm (DN 15)
- 3/4 inch: 19 mm (DN 19)
You're probably wondering what the names are all about. The inner diameter of the garden hose is always given in inches. For this reason, it is important that you know the diameter in millimeters for each inch. This is the only way you can be sure that you have selected the right model. Not every manufacturer specifies the hose diameter on the packaging. You can also refer to the DN information, which is standardized according to DIN EN ISO 6708.
When choosing the garden hose size, it depends on where you are going to use it.
Notice: Faucet and pipe diameter are given in either inches or millimeters depending on the model and manufacturer. Check the dimensions for the hose in advance before deciding on one.
other sizes
In addition to the standards already mentioned, there are other sizes in which garden hoses are available. Garden hoses are manufactured in diameters from 6.3 to 50.8 millimeters, which are suitable for the majority of households in Germany and Europe. The following list gives you an overview of the other hose diameters:
- 1/4 inch: 6.3 mm (DN 6)
- 1 inch: 25.4 mm (DN 25)
- 1 1/4 inch: 31.7 mm (DN 32)
- 1 1/2 inch: 38.1 mm (DN 38)
- 2 inch: 50.8 mm (DN 50)
Notice: Garden hoses with larger diameters are better suited for stationary use, such as supplying an irrigation system. Thinner hoses, on the other hand, are great for hand watering, hard-to-reach places, and filling watering cans.
frequently asked Questions
How do you choose the right garden hose?You must select the hose depending on the outside diameter of the fitting or hose cuff. That means if you want to connect the hose to a faucet with an outside diameter of 19 millimeters, you need a 3/4 hose. Other values are not important for compatibility. The garden hose should never be chosen too large or too small for it to function optimally.
What are garden hose adapters used for?An adapter is necessary if the hose does not have the right inside diameter for the outside diameter of the fitting. The hose can be attached to the fittings via the adapter without a complete replacement, which makes it possible to use it without great expense. The adapter is attached to the fitting and the hose can then be easily attached.
What happens if the garden hose doesn't fit?If you have chosen the wrong diameter, a variety of problems can arise. For example, if you select a hose with an inner diameter that is too large, there will be a loss of pressure. As a result, the water no longer comes out of the hose with the usual force. On the other hand, if the hose is too small, the pressure is too high and permanent damage is possible.
How can several hoses be connected to each other?If the garden hoses are too short, you can connect them to each other using hose sleeves. In this way you get a significantly longer connection, which is possible with any hose. Just make sure you use the larger ID hoses first and end with the smallest. This allows the pressure to stabilize better.
