The ICC's cricket committee has urged MCC to "strongly consider limiting the dimensions of cricket bats" amid concerns over the balance between bat and ball.
At the conclusion of a two-day meeting at Lord's, the committee - chaired by former India spinner Anil Kumble - announced a series of recommendations that will be taken forward to the next ICC board meeting and chief executives' committee in July.
Addressing the issue of bat size, amid spiralling run-rates, a statement read: "MCC sought the committee's guidance on the desirability of making changes in order to redress the balance between bat and ball.
"The committee received a research paper from MCC citing a wealth of scientific and statistical evidence showing bats have become more powerful in recent years, primarily due to having larger 'sweet-spots'.
"The committee's view was that MCC should strongly consider limiting the dimensions of cricket bats to help achieve a better balance between bat and ball."
A number of issues relating to Test cricket, including day-night matches, were also high on the agenda at Lord's.
The cricket committee's statement continued: "There was unanimous agreement from committee members that the current structure of international cricket needed to change.
"The committee was very supportive of the efforts to widen the audience for Test cricket across all member countries and acknowledged the success of the inaugural day-night Test between Australia and New Zealand in Adelaide.
"It stressed, however, that day-night Test cricket needs to be delivered to a consistently high standard across all member countries if the concept is to be successful, noting that the combination of ball, pitch, lighting levels and environmental conditions needed to allow for an even contest between bat and ball at all proposed day-night Test venues."
