What do we mean by 'Capacity'?
Chicago screw post come in a variety of lengths and we need to determine what size length to use of your custom made order.
How much you intend to put inside your portfolio, determines what size screw posts we supply, but also what width spine we make.
If you already have the contents that you are placing inside it, the first option would be to simply stack them up and measure them.
If you haven't got what it you are putting in there, the photo above is 20 pages of 175gsm paper. 50 pages would obviously be bigger and we would use the appropriate length posts.
The hidden screw post binder below has what we call a standard spine with a 13mm gap. This has 30 x 110micron page protectors in. If your wanted to place 50 of our page protectors in, we would use bigger posts, which in turn would require a bigger spine.
