About the Callaway Great Big Bertha (2023)
The Great Big Bertha irons are the flagship of Callaway's Great Big Bertha family, announced in late October 2022 with retail from 11 November 2022 and catalogued as the 2023 line, sitting above the standard Big Bertha at a super-premium price. The head is a hollow two-piece titanium construction — a forged titanium face on a commercially pure titanium body — with a tungsten speed cartridge of up to 145 grams low in the trailing edge, reviving the titanium-iron idea Callaway last sold in the 1990s Great Big Bertha era. Lofts are moderate for a distance iron, with a 30 degree 7-iron and a 43 degree pitching wedge, and the chart runs from the 4-iron to a 54 degree sand wedge with no gap wedge. Specs below are the standard men's numbers.

Frequently asked questions
What is the loft of a Callaway Great Big Bertha 7-iron?
The 2023 Great Big Bertha 7-iron has a loft of 30 degrees, with a 62.5 degree lie and a 37 inch standard length.
What is the difference between the 2023 Big Bertha and Great Big Bertha irons?
The Great Big Bertha is the titanium flagship: a forged titanium face on a commercially pure titanium body with up to 145 grams of tungsten, sold at a super-premium price. Its lofts are also weaker — a 30 degree 7-iron and 43 degree pitching wedge against 27 and 42 degrees for the steel-bodied Big Bertha.
Are the 2023 Great Big Bertha irons really made of titanium?
Yes. The head is a hollow two-piece titanium construction — a forged titanium face on a commercially pure titanium body — with tungsten used to restore mass low in the head. Titanium's light weight is what allows up to 145 grams of tungsten placement.

- Note on offset: the sources publish offset in millimetres in exact 0.25 mm steps (5.08 mm to 2.54 mm), which convert to round hundredths of an inch (0.200 to 0.100), indicating Callaway authored the ladder in inches; the inch values are recorded. Bounce was not published and is omitted.
- Note on years: Callaway announced the Great Big Bertha family — driver, fairway woods, hybrids and irons — in late October 2022, with all pieces at retail from 11 November 2022 (GolfWRX launch coverage; Forbes, 9 November 2022). The family is catalogued as the 2023 line, hence the model name, while year_introduced records the 2022 announcement per this database's convention. year_discontinued and successor are null — no replacement Great Big Bertha iron had been announced in the sources consulted.
