Q&A for How to Size Your Comic Books for Proper Storage

if you're referring to the 100 page spectaculars that were typical in that era, you will find they fit snugly but fine in a standard Golden Age comic book bag.

In order to store comic books in the best condition, people typically use large boxes. No special type in particular, but a box. If you really do want to keep the comics in the best condition, then you might want to seal them in bags before putting them in boxes.

That's commonly known as "digest size." This format was popularized by publishers such as Archie Comics and DC Comics in the 1970s and 1980s for titles like "Betty and Veronica" and "The New Teen Titans." Digest size comics are smaller than standard comic books (which are typically around 6.75 x 10.25 inches) and are often published in a thicker, book-like format. They are still produced today by some publishers, particularly for children's titles and manga.

For modern day comic books, which typically measure around 6.625 x 10.25 inches, the most commonly used envelope size for shipping is a "9 x 12" envelope. These envelopes are slightly larger than the comic book dimensions, which allows for some additional space for padding or protection during shipping. A4 envelopes are typically used for smaller items such as letters or documents and may not provide enough protection or space for a comic book. It's also worth noting that different shipping carriers may have specific requirements for envelope sizes or packaging materials, so it's a good idea to check their guidelines before shipping any items.
