59pt Chipboard Covers

Match the cover to the finished document dimensions, including any tabs or sheets that extend beyond the main paper. A cover that matches the paper exactly gives a clean edge, while an oversize cover can protect protruding tabs and reduce edge wear. Measure width and height rather than relying only on names such as letter, half size, or legal, because specialty formats may use slightly different dimensions. The punch edge must also remain wide enough for the chosen binding holes without weakening the board. For landscape documents, confirm which edge will be bound before ordering. If the job will be trimmed after binding, allow enough material for the final cut while keeping the punch line safely inside the finished edge.

The main difference is stiffness. A 59pt board gives a document a firm backing and resists bending more than a moderate-weight chipboard. That added structure suits manuals, presentation books, sample sets, and documents that need support during handling. A less rigid option can be easier to turn, punch, store, and mail, especially when the document is thin. For work that needs support without the full firmness of 59pt, 42pt chipboard covers may provide a more flexible balance. Cover thickness also adds bulk near the binding edge, so include both covers when sizing the binding element. The right choice depends on desired rigidity, mailing weight, punch capacity, and how the finished document will be used.

Prepunched covers are convenient when the hole pattern exactly matches the binding supplies and equipment already in use. Confirm the binding style, pitch, number of holes, sheet orientation, and bound edge before ordering. A similar-looking pattern may still be incompatible, and the cover cannot be corrected easily after the wrong holes are made. Unpunched chipboard is more suitable when a custom pattern is needed or when one stock size will be used with several binding methods. Before punching thick board, confirm that the machine is rated for cover material and that the dies are clean and sharp. Punching too many covers together can cause incomplete holes, rough edges, or strain on the equipment, so process them within the stated cover capacity.

A thicker board can be useful for large formats, display pieces, sample books, portfolios, or documents that need greater resistance to bending. It may also suit work that will be stored upright or handled without a supporting folder. 79pt chipboard covers provide a firmer alternative when 59pt does not offer enough structure. The extra thickness also increases weight and can make covers harder to turn, punch, or fit within a binding element. Confirm the punching equipment can handle the board and include the cover thickness when measuring the full document stack. For ordinary reports and manuals, additional rigidity may add bulk without improving usability, so thicker is not automatically the better choice.
