Gas turbine engine airfoil

A gas turbine engine comprising:

• a combustor section arranged between a compressor section and a turbine section;
• a fan section having an array of twenty-six or fewer fan blades, wherein the fan section has a low fan pressure ratio of less than 1.55;
• a geared architecture coupling the fan section to the turbine section or compressor section;
• and
• wherein the fan blades include an airfoil having pressure and suction sides, the airfoil extends in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip, wherein the airfoil has a relationship between a total chord length and a span position corresponding to a curve having an increasing total chord length from the 0% span position to a first peak, the first peak occurs in the range of 45-65% span position the curve either remains constant or has a decreasing total chord length from the first peak toward the 100% span position, wherein the total chord length at the 0% span position in the range of 8.2-10.5 inches (20.8-26.7 cm), wherein the curve is at least a third order polynomial having an initial positive slope.
