Resistance is directly proportional to the length of the wire, and inversely proportional to the cross sectional area of the wire.

R = pl/A, where R is resistance, p is the material's resistance in ohms, l is the length, and A is the cross sectional area in m^2.

As a wire gets longer its resistance increases, and as it gets thinner its resistance also increases because its cross sectional area decreases
