Guide To Portfolio & Box Sizes | Hartnack and Co

Guide To Sizes

We can make items to any size that you require (within reason!) Every item we make is designed to fit around its contents. 

Therefore an A4 or 11" x 14" portfolio is made around that size of paper as opposed to the actual size of the portfolio or box being 210mm x 297mm or 11" x 14".

That said an A4 or 11" x 14" portfolio can be any number of 3-4 different sizes depending upon whether:

  1. An A4 page is being punched and then directly inserted.
  2. Hinge strips are being used to attach the page to the bindings
  3. Page protectors/sleeves are being used and furthermore, whether these are H&Co sleeves or say Pina Zangaro sleeves. 

If either option 2 or 3 of the above is used then we make the portfolio slightly larger. Our rule of thumb is that contents sit neatly onto the inner cover when the folder is closed. We make an 8mm margin (unless you request otherwise) around the inner cover for the outer cover.

This is why you will be asked whether you will be using page protectors or hinge strips, otherwise your pages will hang out over the cover.

If your contents are going to be slightly over the standard ISO or American paper sizes, please let us know.

As a rule, unless you ask otherwise, there will be an 8mm margin around the sheet or page protector in a fabric or leather portfolio. The inside board will be the same size as the sheet or page protector.

For boxes, there is generally a 2mm margin both widthways and lengthways to allow ease of removing the sheets whilst ensuring they are snug enough not to get damaged due to excess movement.

US sizes are different to UK/EU sizes – below we have made a chart showing the approximate equivalents.
