Hi @jcdizzystar
Feel free to check out the Surge Size page, it displays how large the bands are, the tracker itself.. and possible to download / print a sizing guide to see which band suits the most..
https://www.fitbit.com/uk/shop/surge
Consider getting a Blaze instead, as it's less bulky than the Surge (as it doesn't has gps build in though able to use the gps from the phone if desired), has a coloured screen, exchangeable bands (leather and metallic band(s)) available..
Has also the more secure wristband like the Charge HR & Surge.
In case the band breaks on the Surge if out of warranty needing to buy a new tracker..
The Blaze is a bit cheaper than the Surge.
