I think the following article is wonderful and explains a lot of the reasons why things like "width" are desirable on multiple levels.

ROUGH JUSTICE - THE HISTORY, THEORY AND FOLLY OF ROUGHS
By Dr. Michael J. Hurdzan, ASGCA

Roughs, those areas of grasses cut higher than fairways and bordering them like a fur collar on a coat, have become a common form of hazard on golf courses; perhaps too common and to the point of ruining the game. A look at the history, theory and folly of rough might serve to refocus our thinking and restore some vital elements back to the game of golf - like strategy for example.
First the folly. There seems to be an attitude amongst organizations that hold golf tournaments to feel that they need to defend par, the honor of the golf course, or the tradition of their competition. These bodies must worry and fret that a competitor might post a score of perhaps 20 under par or better, and that this somehow would diminish the value of their championship, and having a deep rough will protect against that. The most obvious overuse and abuse of rough was once seemingly the sole purview of the US Open, but at Carnoustie in 1999 the practice was extensively employed, and even Augusta National started to grow rough to repel Tiger attacks. William "Hootie" Johnson, Chairman of Augusta National, said, "These young men are hitting the ball a long way. We (Augusta National) felt we could no longer let them swing from their heels." Jack Nicklaus added, "Now Augusta National looks like a U.S. Open Course". Tournament play might be one thing but many golf courses and country clubs are even trying to grow U.S. Open roughs for everyday play.
The theory of rough is that if a competitor is not "sure" with his shots and can’t keep them within the narrow confines of the manicured heaven of the fairways, then his ball may come to rest in the manicured purgatory (because it isn’t easy to get out) of the rough. Typically the fairways are 28 - 30 yards (25 to 27m) wide and mowed at ½" (12mm), with perhaps a "friendly rough" (talk about an oxymoron) of 1 ½" to 2" (37 to 50mm) high grass while the rough is mowed at 4" to 6" (100 to 150mm) high. "Real Rough" is usually classified as "jungle". At many competitions the rough has been so fertilized and watered, that forecaddies are required to spot the ball when it lands, and place a small flag by it so the competitor won’t lose his golf ball. Then the player is expected to thrash the ball out, for there is virtually no hope of hitting a real golf shot, and get on with his game.
The difficulty of rough for the golfer is, of course, trying to get the clubface on the ball to impart backspin, when it is nestled like an egg in a nest of leafy green vegetation. Competitors have injured wrists and backs trying to hack their way to freedom. When a ball is struck with virtually no backspin, it’s commonly called a "flyer" because it travels farther on a lower trajectory. Perhaps these shots should also be called "runners" because it more aptly describes how the ball reacts when it hits the ground. The golfer’s misery caused by rough are compounded by today’s penchant for ultra fast greens, which in turn means they are flatter, with little or no frictional resistance to roll because of the micro fine mowing height of greens, with no grain, making it virtually impossible to stop even a shot with lots of backspin.
A shot from the competitive rough to a modern green is more luck than skill. In fact one only needs to look at the hot new golf equipment of recent times which include lofting irons, utility woods that promise being able to dig out the golf ball and give high trajectory shots that stop quickly, and golf balls designed with dimple patterns to produce high, soft shots. Many club fitters are encouraging customers to not even buy 2, 3, and 4 irons and instead substitute more utility woods and wedges to handle flat, firm greens and deep roughs.
In my 50 years of being around the game, I can’t ever remember one person saying, "gosh, I love hacking golf shots out of ankle deep roughs," and I honestly don’t expect to hear that in my next fifty either. Shots out of the rough are no fun and can even be downright discouraging, which isn’t why we love and play the game. You might ask, "but isn’t that the purpose of a hazard (of which I have just established it is) to impose a penalty on a wayward shot?" Of course it is, but when it is overused it will destroy any strategic qualities the golf course might offer and simply makes it a penal golf course.
In speaking again about Augusta National, Jack Nicklaus said, "It’s changed the nature of the golf course. The Masters has always been a more difficult golf tournament than any other; open fairways with hard, fast greens. Bobby Jones wanted it to be a second shot course." Ben Crenshaw said of the Year 2000 Augusta roughs, "I would say what it has done is to make the course less interesting. This course does not play like it did before (the added rough). It was the most vastly interesting course I had ever seen because it was not dictated to where you had to put your drive. There were some spots where you wanted to be in the rough."
The Old Course at St. Andrews has wide landing areas with virtually no rough and hence it offers multiple avenues between tee and green, which is the essence of strategy. Oh, sure there is a fair amount of gorse and areas of long grass, but these are not formalized on either side of the fairway like a noose around a condemned man’s neck. Not only is there no design creativity in simply ringing a fairway with rough, it is boring, artificial, slows play, and puts a premium on mechanically hitting straight shots, instead of allowing golfers to invent creative, recovery golf shots.
At this point I trust I still have a readership, and that I have sufficiently established the theory and folly of rough. To further validate my points I believe it is instructive to now look at the history of rough.
In the earliest days of golf some believe it was a game first played by the Dutch on ice, and later by Scots on linksland, mostly in the late fall to early spring when native grasses were short and dormant after a season of grazing by livestock. In the spring and summer, grasses were at their optimal growth and since no mowing was done, the entire golf course or "green" looked like rough, making it easy to lose the expensive feathery golf balls.
At some unknown point in the last half of the 1800’s, the game became popular enough that efforts were made to keep summer grasses shorter, first by increasing the herd size of grazing animals, then using men with scythes and sickles, and still later by horse drawn mowers. Each of these progressions resulted in more precisely controlled turf heights and more discrimination about where they should occur. Obviously the animals didn’t give a hoot so to speak, whether they were grazing on a tee, green, fairway or rough, and so they nibbled everything to the same height. The guys with the scythes and sickles were a little more cerebral about what they were doing, but not much, for their job was to cut the grass, probably once or twice in the late spring or early summer, everywhere, and probably at the same height. (If you have ever cut large acreages with these tools you can relate to the imprecision and difficulty involved.)
