Clipboard packs commonly include memo/small sizes (6" x 9"), letter-size formats (around 8.5" x 11"), intermediate sizes such as 9.25" x 13", and extra-large/legal sizes (about 11.5" x 17.4").
Packs accommodate a variety of paper formats: memo-size (6" x 9"), standard letter-size (8.5" x 11")—often A4-compatible—and larger legal or extra-large formats for documents and sketching.
Some packs include clipboards sized for both portrait and landscape use, or feature boards large enough to be used in either orientation; at least one set explicitly includes one portrait and one landscape clipboard.
Clipboards in packs are commonly made from wood or hardboard, medium-density fiberboard (MDF), or plastic; many listings also note metal hardware for the clips.
Wood and hardboard clipboards are described as sturdy, non-toxic, and long-lasting with secure spring clips; plastic clipboards are described as durable or tough in construction.
