Comic Book Bag & Board Size Guide
Comic books have changed size over the decades, so one bag and board does not fit every book. Pick the size that matches the age of your comic, then match the board to the bag. If you are unsure, measure the comic and compare it to the sizes below.
Comic size by age
| Age of comic | Typical years | Bag | Backing board |
|---|---|---|---|
| Current / Modern | 1970s to today | Current bags, 6-7/8″ x 10-1/2″ | Current boards, 6-3/4″ x 10-1/2″ |
| Silver / Regular | About 1956 to 1969 | Silver / Regular bags, 7-1/8″ x 10-1/2″ | Silver boards, 7″ x 10-1/2″ |
| Golden Age | About 1938 to 1955 | Golden Age bags, 7-5/8″ x 10-1/2″ | Golden boards, 7-1/2″ x 10-1/2″ |
| Treasury / oversized | Large-format editions | Treasury bags, 10-1/2″ x 13-1/2″ | Bag only |
Not sure where a book falls? Comics from the 1970s can go either way. Try the Current size first, and step up to Silver / Regular if it feels tight.
Thick comics and trade paperbacks
- Thick or square-bound comics: use a thick bag so the spine is not squeezed. We make Current thick bags (7″ x 10-1/2″) and Silver thick bags (7-1/4″ x 10-1/2″).
- Trade paperbacks: a Current backing board inside a resealable Silver-size bag is the usual fit. Thickness runs from about 1/8″ to 1/4″.
- Resealable bags: the adhesive strip lets you open and close the bag without taping it. See Current resealable and Silver resealable.
Polypropylene or Mylar?
Polypropylene bags are clear, affordable and right for most collections. For your best books, Maxlites 2 Mylar bags are a heavier, longer-lasting option, made in Current, Regular and Silver sizes. Whichever you pick, plan to swap bags and boards every few years.
Storing your comics
Once your comics are bagged and boarded, store them upright in a comic storage box. Short boxes fit standard comics, and long boxes hold more. Graded comics have their own graded comic storage boxes.
