The required watch strap/bracelet length depends on
wrist circumference, potentially adding length for wearing over a sleeve (wetsuit/flight suit)
whether this is a one or two-part strap or a bracelet. Bracelets usually have removable links or more links can be added. There may be a micro-adjust or a diver's extension on the clasp
lug-to-lug distance in case of a two-part strap (the lug-to-lug distance must be subtracted from the total strap length or the strap will be too long. With any strap, you want an excess length beyond the last useable strap hole so that you can tuck the tail end into the strap keeper(s). Usually, 1.5" past the last hole is sufficient. You don't want the tail end to protrude too far.
On NATO and ZULU straps you want 2 inches past the last hole. The length must be sufficient for the style in which you tuck in the strap end. I like to fold mine over and tuck the tail in so it doesn't stick up.
This is one of my NATOs folded over and tucked in on itself. Just enough length to not slip out of the keeper and short enough to not stick out awkwardly.
