Fairway bunkers: measure the lip before you pick the club

A drive finishes in a fairway bunker 155 yards from the green. The ball sits on clean sand, 1.5m back from a lip 60cm high, and for many club golfers 155 yards is a 7-iron. Hit at the 16.3° launch angle of a PGA Tour average 7-iron, the ball rises 29cm for every metre it travels, so it is 44cm off the ground when it reaches the lip. It hits the face of the bunker. A 9-iron, launching at 20.4°, is 56cm up and still catches the top. From that spot no iron reaches the green, and the shot is a wedge back to the fairway.

Launch angle sets how steeply the ball climbs. Over the first two metres gravity takes about a centimetre off the height of a ball leaving an iron at 100mph, so the climb is close to a straight line.

Distance behind the lip each iron needs

The launch angles below are PGA Tour averages for the 7-, 8- and 9-iron as published by GolfMagic. The 6-iron line uses the R&A and USGA’s 2019 study of club golfers, measured with Trackman on natural grass. In all four CONGU handicap categories the average launch was between 11.7° and 12.5°. That is the launch of a tour player’s 5-iron.

Club	Launch	Rise per metre	Behind a 30cm lip	Behind a 50cm lip	Behind a 1m lip
6-iron (club golfer)	12°	21cm	1.4m	2.3m	4.7m
7-iron (tour average)	16.3°	29cm	1.0m	1.7m	3.4m
8-iron (tour average)	18.1°	33cm	0.9m	1.5m	3.1m
9-iron (tour average)	20.4°	37cm	0.8m	1.3m	2.7m

The distances are measured flat along the ground, from the ball to a point directly below the top edge of the lip, and they are the minimum at which an average launch just clears it. Treat them as a best case. They come from shots off grass with a normal ball position. Peter Finch, the PGA professional, tells Golf Monthly to play an 8-iron from the middle of the stance in a fairway bunker and to “move it slightly further back” for a longer iron. A ball further back meets the club with less loft, and Trackman says launch angle follows dynamic loft closely, so most fairway-bunker shots will come out lower than the table.

High handicappers’ launches vary more

The R&A and USGA study recorded the spread of launch angles as well as the averages. With a 6-iron, tour professionals had a standard deviation of 2.4°. Category 4 golfers, the highest handicaps in the study, had 5.1° around an average of 11.7°. Assuming a normal distribution, about one 6-iron in six would have left the face below 6.6°. At 6.6° the ball rises 12cm per metre and needs 4.3m behind a 50cm lip, almost twice the table’s figure.

Any launch below the average catches the lip at the table’s distance, and a high handicapper’s launches vary twice as much as a tour player’s. Find the club the table allows, then take the next one up in loft.

What a fairway bunker costs at each handicap

Shot Scope’s 2026 data, published by Golf Monthly in July, compares the average score to par on holes where the tee shot found a fairway bunker with holes where it didn’t. The same article gives the figures for approach shots that found a greenside bunker.

Handicap	Extra shots, fairway bunker	Extra shots, greenside bunker
0	0.19	0.43
5	0.29	0.48
10	0.36	0.46
15	0.45	0.52
20	0.55	0.42
25	0.58	0.41

A scratch golfer loses less than a fifth of a shot to a fairway bunker. Between 15 and 20 handicap the two columns cross, and from 20 upwards a fairway bunker costs more than a greenside one. Golf Monthly, citing Shot Scope, also gives the average amateur a 26% chance of hitting the green in regulation from a bunker, against 55% from the rough. A shot that stays in the sand costs at least one more shot. Finch warns that “being too aggressive could leave you playing again before reaching for the rake”.

Setting up without touching the sand

Rule 12.2b bars touching the sand with the club in the area just ahead of and just behind the ball, and in a practice swing or the backswing. A breach costs two strokes in stroke play or the hole in match play. Hover the club above the sand at address. Finch’s set-up is to shuffle the feet in for a firm stance, keep about 60% of your weight on the lead side, and “grip down the club a little”. Gripping down, he says, helps “to prevent the club from digging into the sand”.

Measure the height of your knee from the floor and the length of your shoe in centimetres before you play, so you have a gauge for each number. In the bunker, judge the lip’s height against your knee, then count shoe lengths from the ball to the spot below the top of the lip. Convert the shoe lengths to centimetres and divide the distance by the height. Take a 9-iron only if the answer is 2.7 or more, an 8-iron at 3.1 or more, a 7-iron at 3.4 or more and a 6-iron at 4.7 or more. A high handicapper then takes one club more loft. Below 2.7, take a wedge and aim for the widest part of the fairway.
