That's the sort of beard, guilegr, that looks good at any length but I think that your current job's requirement for only1/4 inh is a bit restrictive to say the least. Anyway, how do they enforce the rule, come round with a measure? See how far you can push the rule; I reckon that at least a month's growth ( 1/2 inch)  should be easily achieved. Best of luck!

Keep growing. Stay bearded!
