An effective stroke distance when climbing up a pole is 8" to 10".

Explanation:

In order to have a safe stroke upwards, the distance of the stroke has to be strictly restricted. It is so because, any attempt to make a larger stroke can make the climber lose his grip on the pole.When descending down a pole, it is preferable to keep the steps longer, but while climbing up, the strokes should not be more than 8" to 10". Also, the climber is advised to keep his knees about 8 inches apart from the pole while going up the pole.
