Lofts compared

- i3+
What the differences mean
At the 7-iron, the i3 O-Size is 34.5° and the i3+ is 34.4°, a 0.1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the i3+ should carry a yard or so further with that club, on a slightly lower, shallower flight than the i3 O-Size. Across the 11 clubs both sets share, the differences roughly cancel out, with the largest gap at the 9-iron (42.5° vs 42.7°). The pitching wedges are 47° and 47.2°; the stronger one leaves a 3° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the i3+ 7-iron sits 0.2° flatter (62.5° vs 62.3°), which nudges start direction slightly right for a right-hander.
The sets are built differently: the i3 O-Size runs 3-iron to LW (11 clubs), the i3+ 2-iron to LW (12 clubs).
Both are game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
Both heads are listed as investment cast. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The i3+ arrived 3 years after the i3 O-Size, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept. Here the 7-iron loft moved from 34.5° to 34.4°.
Which should you choose?
The i3+ is the weaker-lofted set — up to 0.2° weaker than the i3 O-Size. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.

Frequently asked questions
Is the Ping i3 O-Size stronger lofted than the i3+?
No. The i3+ is the stronger-lofted set: its 7-iron is 34.4° against 34.5° for the Ping i3 O-Size, 0.1° stronger and worth a yard or so of extra carry.
What is the loft difference between the Ping i3 O-Size and i3+?
At the 7-iron the difference is 0.1° (34.5° vs 34.4°). The largest gap on a shared club is 0.2° at the 9-iron, and 7 of the 11 shared clubs differ.
Are the Ping i3 O-Size and i3+ aimed at the same golfer?
Yes. Both are game improvement irons, built for roughly 10 to 25 handicaps. Choose on feel, looks and gapping, ideally after hitting both.
Do the Ping i3 O-Size and i3+ have the same lie and length?
Not exactly. At the 7-iron the Ping i3 O-Size is 62.5° lie and 36.75 inches, the i3+ 62.3° and 36.75 inches. Both can be bent or built to your own fit.
