I have worked a lot with Arthur Little on this one. In general, the forward tees for recreational women, who we believe average no more than 140 yards on their tee shots, should be in the 3800-4400 yard range.
For some simple math, take that 140 yard shot and assume 120 yards average for second shots as max.
Average 130 x 36 regulation shots and you come out to 4680, but no one wants to hit full shots on every second shot. So, assume 100 yard average second shot and multiply 36 x 120 and you get 4320. And any longer than that, you create a bunch of max seconds and even thirds on most par 4 holes, and we all know how boring long par 5 holes are for us as men.
If you use the second shot as 2/3 the tee shot, at about 92 yards you get 4176.
You get some resistance from traditionalists at first (of course the men who have a bad attitude anyway about women on the golf course) and even from some better women, but after they try them, golf becomes a lot more fun. One decent player played the poorly named "express tees" at La Costa (about 4300 yards) and said she could have hit 13 of 18 greens, so why didn't we make all 18 reachable in regulation?
Obviously, we would, but natural features and some cross hazards come into play, and mere distance on any individual hole isn't the only factor, but I believe you should shoot for 18 and accept no less than 14 holes they can play in regular figures.
It is also affected by other lengths by tee, presuming you want all golfers playing to same par and similar shot values. (I see lots of people here write about all sorts on different arrangements, but its not generally acceptable to most golfers) Lastly, as mentioned, both roll and uphill shots affect the shorter hitters far more than long ones, because they get more roll proportionally. So if your course has hills or is damp, that has to be factored in.
In general, if you start with the back tees, then the next tee should play about 92% of the max length, then 84%, then 76%, then 68%, and finally maybe 60% for the forward tees. So a 7250 yard course, to play proportionally should be 6670, 6090, 5510, 4930, and 4350 for all players on the correct tees to get the same club value into greens, more or less, on their full shots. Most really start with the back men's tees (the 92% value, and ADD for championship tees)
The typical tee blocks are separated by 20-30 yards, but this gets everyone to the same landing zone (more or less) but leaves proportionally longer second shots for forward tee players. By that measure, using 20 yard splits, the 7250 course would come out at the typical 6890, 6530, 6170, 5810 and (with a bigger split of 40 yards) 5090. Most of those distances are too long for those who play them, and of course, 7250 is about the minimum for top players, so using proportional distance is hard, and maybe you have to accept it being too easy by a bit for the longest players. Or, decide you are really catering to......
Another typical problem is, using the 140 yard tee shot, then 120 for second and third, the max par 5 for the forward tees should be 380 yards, not the 405 recommended by the USGA, so you have to break a few eggs to make this omelet.
