Wind turbine blade

A wind turbine blade having a length of at least 100 meters comprising:

• a root end and a tip end, the blade extending in a spanwise direction from the root end to the tip end, the root end having a circular profile with a root end diameter, and a profile of the blade transitioning into a lift generating profile moving in the spanwise direction from the root end towards the tip end;
• a leading edge and a trailing edge, the blade extending in a chordwise direction along a chord from the leading edge to the trailing edge;
• and
• an inboard region extending in the spanwise direction from the root end to a distal end, the inboard region having a length defined between the root end and the distal end;
• wherein in the inboard region, the chord of the blade is within 5% of the root end diameter and the inboard region has a length of at least 10% span of the blade;
• and
• wherein in the inboard region a thickness to chord ratio of the blade profile strictly decreases from 3% span or less to the distal end of the inboard region.
