Binders And Stock Sheets: How To Determine Capacity?

I have started moving my collection from stockbooks to stock sheets. Despite some variable-size pains, the transition has been smooth enough. However, I'd like to know how to determine the binder capacity for stock sheets.

I have one large Scott Specialty binder, and four medium-sized G&K Nassau ones. I'd estimate that a Scott Specialty binder holds about 80 sheets, and a G&K Nassau one about 40...

But I am afraid to put either too many or too few sheets into a binder.

And I have no idea what the right capacity is. Unfortunately, the binder manufacturers often don't bother to give their estimate, or they only give estimate for album pages, not for binders.

Is there some formula that would tell you how many stock sheets should fit into a binder depending on its depth in inches?

Of course, I could just try fitting as many sheets into a binder as I can -- but what if this will damage sheets and/or stamps?

And I fit too few sheets, won't extra space cause the sheets to bend?

Any ideas? Thanks!

I don't think too few sheets is ever a problem, as you could always select a smaller size binder or fill the binder with blank pages if you felt there was some need to store it that way.

As for the number of stock sheets per binder, a lot depends on the type of stock sheets you use and whether they are single or double sided. I don't believe there's any magic number for such storage, you just don't want to overfill the binder to the point that the stamps get too compressed or it becomes difficult to page through the content of the stock pages. I always like to underestimate the number of sheets and then should it become necessary to add one or two pages as my collection grows, it doesn't become a major problem.

Also, don't forget that stock book pages, albums, binders, etc., always do better if they are stacked in a bookcase. Never store them flat (at least not for any period of time).
