In Germany, a "Maxibrief" is a postal category for flat shipments up to 353 × 250 × 50 mm and 1 kg. Any box that stays within these limits qualifies for letter-rate postage. The cartons in this category are built to match those limits exactly.
The inner dimensions determine whether your item fits. Not the outer dimensions.
The carton has its own weight, which counts towards the 1 kg maximum. Larger sizes weigh more than smaller ones.
Brown is cheaper because it is unbleached. White looks more polished and works well for customer-facing shipments.
All maxi letter cartons in this range have a tab-lock closure (FEFCO 0426). No tape needed, assembly takes seconds.
Standard German letterbox slots are roughly 30 to 40 mm tall. Only the flattest sizes (up to 35 mm outer height) fit through reliably.
The E-flute board and the carton edges protect most items sufficiently. For sharp-edged or fragile goods, plan for lightweight cushioning.
| Name | Outer dimensions (L × W × H mm) | Inner dimensions (L × W × H mm) | Suitable for | Limitation | When useful |
|---|---|---|---|---|---|
| MB 0 | 180 × 100 × 30 | 176 × 96 × 27 | Very flat items (data carriers, cards) | Only 27 mm inner height | Letterbox delivery required |
| MB 1 | 160 × 110 × 50 | 150 × 105 × 46 | Small, compact items (jewellery, USB sticks) | Smallest footprint in range | Tiny items that need 50 mm height |
| MB 2 | 180 × 130 × 45 | 170 × 125 × 41 | Phone accessories, small electronics | 170 × 125 mm inner area | When MB 1 is too narrow but A5 too large |
| MB XS | 225 × 145 × 35 | 220 × 136 × 33 | Flat books, documents up to approx. A5 | Only 33 mm inner height | Flat enough for letterbox fit |
| MB 3 (A5) | 240 × 160 × 45 | 230 × 150 × 41 | Books, textiles, cosmetics sets | 230 × 150 mm inner area | All-rounder for mid-size goods |
| MB 4 (A4) | 320 × 225 × 50 | 315 × 220 × 45 | A4 documents, catalogues, clothing | 45 mm inner height | When A4 format is needed |
| MB 5 | 350 × 250 × 50 | 340 × 245 × 46 | Larger textiles, flat household goods | Largest option; beyond this use a shipping carton | Maximise the available footprint |
If customers need to return items easily: the tab-lock closure allows reuse without tape. The recipient needs no tools and can use the same carton for the return.
If the recipient is not home during the day: all maxi letter carton sizes fit into DHL parcel lockers (Packstationen). Delivery success rate goes up, fewer shipments bounce back.
When order volume spikes, every second of assembly time counts. Maxi letter cartons ship flat and need no tape dispenser. Ideal for pre-picking on pallets.
For static-sensitive goods or sharp edges, the E-flute alone is not enough. Place the item in an anti-static bag plus tissue paper, and choose one size up so the cushioning fits.
Maxibrief is a German postal category for flat shipments up to 353 × 250 × 50 mm and 1 kg. Sending at this rate is significantly cheaper than parcel shipping. The cartons on this page are sized to fit within those limits.
FEFCO 0426 is a standardised box type with a tab-lock base and lid. It does not require tape for closure and can be opened and reclosed multiple times without damage.
E-flute (also called micro-flute) has a wave height of roughly 1 to 1.9 mm. It is sturdy enough for lightweight goods while keeping the overall carton height low.
Place the recipient address on the top face. The sender address goes on the top face or on one of the narrow sides. Write legibly. Avoid handwriting on dark cardboard.
Yes. They are delivered flat and stack efficiently. The exact number per pallet depends on the carton size.
Yes, as long as the carton fits through the slot. The flatter sizes (up to 35 mm outer height) fit into standard Deutsche Post postbox openings.
The carrier may reclassify it as a parcel and charge the recipient additional postage. Weigh and measure before shipping to avoid this.
Yes, if the shipment contains only goods plus an invoice or delivery note and is marked as "BÜWA." Personal letters or messages are not allowed in a BÜWA shipment.
