Folding A3 and larger pages


Most documents are of A4 size but a few may have a larger paper size. It is not unusual for maps and drawings to be A3 or even A2 size. Land Registry title plans for most houses are A4 size but if a larger area of land has been registered, for example an estate road or agricultural land, the title plan may be A3 or larger. Before the 1970s many Conveyances were about A3 size (not exactly A3 as that is a modern paper size but approximately A3).

Although it depends on how many A3 (or larger) documents there are, usually copies of documents are collected and bound together in A4 size with larger pages being folded into A4 size.

Folding A3 sheets

The width of an A3 sheet is the same as the length of an A4 sheet so it is fairly easy to fold an A3 sheet into A4 size like this:

Folding sheets which are larger than A3

Folding sheets which are larger than A3 into A4 size is a bit more complicated but the key is to use a diagonal fold. The video here shows how to fold an A1 sheet into A4 size - note the diagonal fold at the bottom left shown at the end of the video. 

The diagonal fold ensures that there is a single thickness of paper in the margin where the sheet is to be bound. The video shows the sheet being folded into exactly A4 size and this is suitable if the pages are to be bound in the middle of the left hand edge - e.g. if two holes are punched and the pages are bound together using ribbon, or in a ring binder, or in some other way which does not involve binding all the way down the edge. If, however, comb binding, or any other kind of binding which uses the whole A4 length, is used you may need to fold the sheets so that, in the folded state, they are slightly longer than A4 size with the bottom (where the diagonal fold is) protruding by about half an inch. This is to ensure that the binding does not catch the corner of the diagonal fold.         

Folded sheets should generally be printed only on one side. 

Ensuring page numbers are visible when the sheets are folded

When you fold an A3 or larger sheet you are folding it so that it will be bound on its shorter side, whereas in the PDF generated by DCS the page numbering will have imposed on the assumption that the page will be bound on the longer side. Consequently the page number will not appear in the usual position, but as long as a page number is at least easily visible somewhere when the page is in the folded position (not under the fold and not too close to the binding) that is fine. If the page number is not easily visible in the folded position use a pen to write the page number at the bottom of the folded page.
