Tiny is up to around 2ft tall, (though I'd tend to smaller), at 2ft, 20lbs theyre essentially the size of a small dog, moderate str and con. With Str
Gnome
Size Tiny
Fleetfoot - You are fast for your size and have a Spd 30 ft. In addition you can dash through the spaces of creatures of medium size or larger without suffering opportunity attacks.
Evasive You also get advantage on dexterity checks to dodge an attack or escape from being grappled
Lightweight: Because of their lightweight gnomes can fall up to 60 ft without taking damage, beyond this they only suffer half the damage of a fall.
Gnomes can use daggers, shortswords, slings, handbows, spears and grenades
I also give my gnomes Swarm Instincts - Gnomes are eusocial creatures, used to swarming together to achieve tasks that a beyond the capacity of an individual. When working on a task with their allies, a gnome instinctively understands where it needs to be to be most useful to the group. Each gnome adds +2 to the ability checks used to achieve a task. In addition a gnome can use its reaction to reroll the failed check of another gnome as it moves in to help.
