Grote brievenbus voor A4 en grote post

Mail that does not fit through a slot ends up on the doormat or has to be collected. A large mailbox solves that, without immediately putting a parcel locker in your front garden. The Maximus and WALL are the models to look at for this.

Why a large mailbox makes the difference

A standard mailbox is designed for envelopes, not for everything that lands in it today. A magazine, a catalogue, a sturdy C4 envelope or a bundle of parcels: A4 size does not always fit through a narrow slot. You notice it immediately from the pile on the kitchen table or from a note saying you need to collect your post.

A spacious mailbox removes that threshold. The opening and the interior are large enough for A4 post and thick items, while the model itself remains a calm element on your facade. That is exactly what the Maximus and the WALL aim for: more usable space, without the design becoming clunky.

When choosing, pay attention to three things. How wide and high is the slot, how deep is the box, and does the post inside stay protected from rain and prying eyes. A large mailbox benefits from a good flap or canopy and from sturdy mounting.

The Maximus and WALL: space in two characters

The Maximus is the model for anyone who really expects a lot of post. You recognise it by its generous size and its pronounced, sleek shape. It is made of aluminium, which keeps it low maintenance yet sturdy in use. Where the model allows it, you can opt for a parcel compartment, so that larger items also stay safely out of sight.

The WALL is the understated variant. It looks flatter and calmer on the facade, but still offers room for A4 post and everyday items. Here too, aluminium is the starting point. Both models are available in a wide colour palette: more than 2000 RAL colours, so the mailbox can blend in with your facade, joinery or gate.

If you want certainty about which options belong to which model, such as a combination lock or a parcel compartment, you will find that per model in the range. View all models and compare the Maximus and WALL side by side.

Placement and use of a spacious mailbox

A large mailbox requires a little more attention when mounting. Choose a height that is comfortable for the postman and for you, and make sure the flap can open freely. With a heavier model, solid, fixed mounting is important, especially on a wall that catches the wind.

Also consider the surroundings. A mailbox next to a hedge or under a canopy keeps rain out better. If you want access with a numerical code instead of a key, a combination lock is a practical choice, but check per model whether that option is available.

For the exact requirements around postal delivery, such as the location and height where bpost delivers, we refer to bpost itself. They determine where the postman does and does not ring or insert. That way you avoid surprises and your large mailbox remains optimally usable.

Which large mailbox is suitable for A4 mail?

For A4 mail and thick items, look at the Maximus and the WALL. The Maximus offers the most space and can have a parcel compartment in certain versions. The WALL is more compact but still suitable for A4. Both are available in aluminium and in many RAL colours. Check which options apply per model.

Frequently asked questions

Good to know

Does A4 mail fit in every mailbox?
Not equally easy in every model. The Maximus and WALL are the models we recommend for A4 and large mail. For other models, it is best to check the dimensions of the slot and the box before you decide.
Can I add a parcel compartment or combination lock?
That differs per model. Some versions of the Maximus can have a parcel compartment, and a combination lock is not available on every model. You will find the exact options per model in the range or at an recognised point of sale.
What should I pay attention to when mounting a large mailbox?
Make sure it is mounted securely, at a height that is comfortable for the postman, and with enough free space for the flap. A spot out of the rain or under a canopy helps keep the contents dry. For the exact delivery regulations, we refer to bpost.
