Large Format Poster —
Dress the Big Walls

An empty large wall can be intimidating — and a small poster gets lost there. For walls over 2 meters wide, think big: a large format poster that takes on the role of focal point, or a composition that fills the space with rhythm. Here is how to choose.
Up to 70 × 100 cm: The True Large Formats
Two formats go beyond A1, on a selection of our designs: the 61 × 91 cm, as a poster or in a solid oak frame, and the 70 × 100 cm, as a poster. This is the scale that lets a single piece hold its own above a three-seater sofa or a double bed, with no need for company. These designs are gathered in the Large Format Poster collection.
-
70 × 100 cm — the maximum format, as a poster, for walls of 2.5 m and up
-
61 × 91 cm — poster or oak frame, the large format that stays manageable
-
A1 (59.4 × 84.1 cm) — available across most of the catalog, ideal from 2 m of wall width
-
50 × 70 cm — the versatile large format, solo or in pairs
-
A2 (42 × 59.4 cm) — the balanced intermediate size
The simplest rule of proportion: a single piece ideally covers two thirds of the width of the furniture it hangs above. The center of the image sits at eye level, around 145 cm from the floor. All our formats are printed in HD on premium matte 189g/m² paper — at large sizes, the quality of paper and print is immediately visible. For all the details on sizes: our complete poster size guide.
A Single Large Format, or an XXL Composition?
To cover a very large wall — the XXL wall art poster effect — both approaches hold up. A single 70 × 100 cm gives a clean focal point and goes up in five minutes. A composition of several posters — a triptych of 50×70, or a gallery wall mixing a central large format with satellite sizes — adapts to the exact width of the wall and covers 2 to 3 meters while staying airy.

Create your XXL wall in just a few clicks with our gallery wall configurator — you can preview the full composition before ordering.
Which Designs Work in Large Format?
The larger the format, the simpler the design should be. Mineral textures and Mediterranean architectures take on a remarkable presence beyond A1:

FAQ — Large Format Posters
What is the largest poster format at Cassili-home?
The 70 × 100 cm, offered as a poster. Just below it comes the 61 × 91 cm, available as a poster or in a solid oak frame. These two formats exist on a selection of our designs, gathered in the Large Format Poster collection. Across the rest of the catalog, the largest format is A1 (59.4 × 84.1 cm). Available formats are indicated on each product page.
What poster size for a 3-meter wall?
A single A1 will look small there. Two options go the distance: a 70 × 100 cm on its own as a focal point, or a composition — a triptych of 50 × 70 (about 190 cm wide including the spacing) or a gallery wall of 4-5 posters around a central large format.
How to hang a large format poster without damaging it?
For a 61 × 91 or 70 × 100 poster: use two spaced hanging points. For 61 × 91, choose the framed version only when it is offered. Keep the poster flat against the wall and avoid leaving it rolled for too long before hanging — see our hanging guide.
XXL single poster or composition?
Both make their case now that the 70 × 100 exists. A single piece gives a clean focal point and goes up in five minutes. The composition adapts to the exact wall width, is easy to transport, and evolves with your desires — you replace one poster, not the whole wall.
