Highlighted cells differ between the two sets. Lofts and lies are factory standard.

Lofts compared

Lofts match on every club the two sets share, so the markers sit on top of each other.

What the differences mean

Every club the two sets share has exactly the same loft, starting with a 35° 7-iron. On paper there is no distance or trajectory difference: with the same swing, a 7-iron from either set should launch and carry about the same. The real differences are in how the heads are built, how they look at address and how they feel at impact, none of which a spec table can show. Lie angles and lengths match as well, so any fitting adjustment made to one set would carry straight over to the other.

The sets are built differently: the ZB runs 2-iron to PW (9 clubs), the ZM 3-iron to PW (8 clubs).

The ZB is a players iron and the ZM a blade iron, so they sit one step apart on the forgiveness scale. The ZB is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly scratch to 10 handicaps. The ZM trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits low single-digit handicaps who strike the ball consistently.

The ZB is listed as forged, blended cavity-to-muscle back and the ZM as forged muscleback. 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.

Both sets were introduced in 2008, so this is a choice between two models from the same lineup rather than an upgrade: Titleist designed them to sit side by side for different players.

Which should you choose?

The ZB and ZM share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.

Frequently asked questions

Is the Titleist ZB stronger lofted than the ZM?

No. Both have a 35° 7-iron and the same loft on every club they share, so neither is stronger lofted. The difference is in construction and feel.

What is the loft difference between the Titleist ZB and ZM?

There is none. Every club both sets include has the same loft, including the 35° 7-iron.

Which is better for higher handicap golfers, the Titleist ZB or the ZM?

The Titleist ZB. As a players iron it is the more forgiving design, suited to roughly scratch to 10 handicaps. The ZM is a blade iron, better suited to low single-digit handicaps who strike the ball consistently.

Do the Titleist ZB and ZM have the same lie and length?

At the 7-iron, yes: both are 63° lie and 37 inches long.
