Instead, try to put holds in unusual positions so that you need to climb by laybacking, sidepulling, underclinging, backstepping, and generally moving your body into interesting postions. Sometimes you want to create reachy routes, so maybe you should only put one or two reaches in. Another fix is to put additional foot chips which are higher than the holds that you stand on to make the reach. A shorter person can use the higher chips and locking off lower, make the reach. Another option is to place intermediate handholds, little crimpers that shorter people might use, either statically, or as an intermediate to help them pull to the higher handhold.
Footholds can be chips.
Routesetting Tip Number 3 Use chips as footholds. Remember, you do not need to restrict the feet to using handholds. Put tiny chips on for feet that cannot be used as a handhold. Make them small and slopey, or very tiny edges. Even small edges can be crimped on.
