Please note, my 60-65 axe is in CENTIMETERS. You guys buying the 65-70 INCH axes are going to have these giant deltoids from lifting your arms over your heads for years.

I'm 6'4" and generally use a 60 or 65 cm axe. I believe the advice to go from fingertips to floor is completely wrong. Abraham Lincoln was also wrong in this case. If your axe is long enough to reach the ground, it will be too long. If the slope is so steep that you need an axe, then a short axe will be plenty. If it's not that steep, you probably don't need the axe. Imagine climbing up a hard snow slope where the surface you are plunging the axe into is at waist level or higher. Now imaging dragging your 75 cm axe up over your head about 400,000 times. Arm tired yet? Go short - 60 or 65 max. (25 years experience on glaciers).

I just purchased the 65" length and I'm 6'2" as well. I was stuck between going 65" and 70" but decided why not go with the smaller, lighter, less cumbersome. I don't think I'll miss the 5". You pretty much always keep the thing ahead of you up hill as you ascend and descend... you're not using it to reach downhill certainly, so remember that. The stick idea (above) is helpful.

From what I've learned, 6+ footers use 70cm to 75cm.

65-70...try making a stick that is the different sizes and try it out.
