Custom Literature Mailer Boxes

Flat Mailer vs. Standard Mailer Box

A literature mailer is built flat and wide rather than deep, since it's sized around printed materials, catalogs, brochures, lookbooks, not a bulkier product. A standard mailer box is typically deeper and closer to cube-shaped, built to hold a physical product with some clearance around it. Using a flat mailer for printed materials avoids the wasted internal space a deeper box would leave around a stack of paper, and it usually costs less per unit since it uses less board.

Sizing a Literature Mailer Around the Contents

A literature mailer is sized to the printed piece's actual dimensions plus a small clearance, not a generic paper-size category. A single catalog needs less depth than a bundled set of brochures or an insert card. Sharing the exact dimensions of what's being mailed, and how many pieces are going in together, is what gets the mailer sized correctly on the first attempt rather than needing a second round of adjustment.

Auto-Lock Bottom Construction

An auto-lock bottom assembles by folding into place without tape or adhesive, and holds its shape under the weight of stacked printed materials. This construction style is standard for literature mailers because it assembles quickly at packing time and doesn't add extra material the way a taped or glued bottom would. The same auto-lock mechanism works across different literature mailer sizes, though a materially larger or smaller mailer still needs its own dieline sized to those dimensions. Board weight matters here too, a mailer carrying a single lightweight catalog can use a lighter corrugated flute than one carrying several bundled brochures, since the bottom panel needs enough rigidity to support the stacked weight without sagging in transit.

Interior and Exterior Printing

The exterior surface carries the shipping-facing brand identity, while a printed inside panel, visible the moment the recipient opens the mailer, turns that moment into a branded one instead of a plain kraft or white reveal. Interior printing is optional and adds cost, so it's worth deciding early whether the unboxing moment matters enough for this specific mailing to justify it, rather than defaulting to it for every order regardless of the contents. A press kit or a first client mailing might justify the added cost, while a routine catalog reprint sent to an existing customer list usually doesn't need it.

What to Send for a Literature Mailer Quote

Getting an accurate quote starts with sharing the printed piece's real dimensions and how many are being mailed together. Orders start at a minimum of 50 units, and a dieline and digital proof review are included on every order at no extra charge before anything goes to production. Once the proof is approved, production typically begins and runs from 7 business days, with free US shipping included. For anyone who wants to check the board weight and print quality before committing to a full run, a sample kit ships for a $44.99 shipping charge, credited toward the first order.
