Dimensions of herbarium specimen sheets

I am trying to gather information on Herbarium Specimen sheet
dimensions, and would appreciate information from any Herbarium,
Botanic Garden or conservation unit that has had involvement with
such collections.

I would be particularly interested in any commonly encountered sheet
sizes both past and present together with the institution or person
that made the collection. Additional information such as the paper
dates, material, furnish etc would also be extremely helpful. Thanks
in advance,
