Widest size is know as Full width approx 44mm, mid is around 38mm and slim or skinny tends to be around 31mm
Softer and larger is better for outdoor skating for example 78a is usually the softest a wheel can be, and 78a to 85a is the usual outdoor wheel hardness. some wheels are design for skate parks, these tend to be harder 92a and upwards to 101a and even 103a is some cases.
Artistic , Dance and Jam skating also prefer smaller harder wheels
