Here are pictures showing how Open Goaaal Standard Size can be narrowed for different sizes of garden. When you've narrowed it to the width you require, you can either trim off the excess net or hook it into the side carabiners.
1. This is the maximum width of Standard Size - about 2.0m of black net either side of the goal.
2. This shows about 1.0m of black net either side of the goal.
3. This is the narrowest width - 0.5m of black net either side of the goal. Perfect for narrow gardens where the biggest issue is kicking the ball over the top.
Large size narrows to 1.0m either side of the goal.
