With that in mind, it is important to understand the air-time/ground-time ratios of shots hit with different clubs. The selection of the correct club is vital. You can chip with anything from a 3-iron to a sand wedge depending on the situation, but you must know the following formulas (also illustrated in chart above) to decide which club is required.
When you chip with a pitching wedge, the ball will fly half the distance to the hole and roll half the distance. When you chip with an 8-iron the ball will fly 1/3 of the distance and roll 2/3. When you chip with a 6-iron the ball will fly 1/4 of the distance and roll 3/4.
(By the way, we call this this 6-8-10 Formula because the formula involves the 6-iron, 8-iron and pitching wedge, and the pitching can technically be called a 10-iron.)
These formulas are based on a normal paced, level green (a situation we don't often find on the course), so if you are going uphill you would need to go up one club, and downhill requires going down one club. If the green is fast you again will need to go down one club and if the green is slow you will go up one club. I know this may sound confusing at first, but once you understand the basic formula, it really is just common sense.
Always try to land the ball about 3 feet onto the putting surface and let the ball roll the rest of the way.
