Do Guest Miis have the default height/weight for Mii Fighters?

[firedude953]

Also, is there a difference in height/weight for each Guest Mii?

No. All Guest Miis have the same height and weight.

All Guest Miis have the Height/Weight ratio of 50/50. In-game, this translates to a character weight of 100, putting them on the high-end of Middleweight (If not the low-end of Heavyweight)
