Some Remarks on Aerodynamics
Taper ratio, the ratio of tip chord to the root chord, is an important parameter. A wing with a low taper ratio tends to have downwash patterns that move the lift distribution towards an elliptical one. A low taper ratio leads to larger chords and wing thickness near the root where the bending moments are the largest. It also moves the center of pressure inboard reducing the aerodynamic bending moments. Both of these factors are favorable from a structural standpoint. The most effective wings usually have low taper ratios, particularly when the wings are swept.

Shown below are the wing lift distributions for three types of wings.
