4 Sheet Poster Size UK: Dimensions, Artwork And Printing Guide

Direct answer: A 4 sheet poster is 40 × 60 inches, which is 1016 × 1524mm. It is larger than A1 by roughly 3.1 times in surface area, so A1 artwork should not simply be scaled up without checking proportion, resolution, bleed and safe areas.

4 sheet posters are a familiar large-format advertising size for outdoor and high-visibility indoor display. They are commonly associated with bus shelters, street-level advertising frames, event promotion and campaign posters where the artwork needs to be read quickly from a distance.

4 Sheet Poster Size At A Glance

Measurement	4 sheet size
Millimetres	1016 × 1524mm
Centimetres	101.6 × 152.4cm
Inches	40 × 60 inches
Aspect ratio	2:3 portrait, or 3:2 landscape if rotated

The useful point for print buyers is that 4 sheet is not part of the ISO A-series. A1 is 594 × 841mm, while 4 sheet is 1016 × 1524mm. That difference matters when artwork is being resized from an A1 poster, a Canva layout, or an existing campaign file.

Is A 4 Sheet Poster The Same As A Quad?

No. The wording is often mixed up, especially around traditional poster and cinema formats. A UK quad poster is normally understood as a 30 × 40 inch landscape format. A 4 sheet poster is 40 × 60 inches. In older poster terminology, 40 × 60 inches may also be described as a double quad, but the safest specification for production is always the finished size in millimetres.

4 Sheet Compared With A-Series Poster Sizes

Format	Finished size	Best used for
A1	594 × 841mm	Indoor posters, noticeboards, retail displays and smaller event promotion
A0	841 × 1189mm	Large indoor posters, plan prints, exhibitions and higher-impact wall graphics
4 sheet	1016 × 1524mm	Outdoor display frames, campaign posters, high-visibility event advertising and bus-shelter-style formats

A 4 sheet poster is about 1.548 square metres. A1 is about 0.500 square metres, so a 4 sheet poster gives around 3.1 times the printable area. The aspect ratios also differ slightly: A1 follows the ISO A-series ratio, while a 4 sheet poster is a 2:3 format. That is why scaling A1 artwork up can create unwanted cropping, borders or stretched layouts.

Artwork Setup, Bleed And Safe Areas

For general large-format print, the final artwork size should be confirmed before the design starts. If the poster is being used in a specific advertising frame, follow the frame owner’s artwork specification rather than relying only on a generic print size.

For outdoor media, Bauer’s Station 4 specification gives useful production context: it lists a final printed reference size of 1016 × 1524mm, half-size creative dimensions of 508 × 762mm, a half-size safe copy area of 495.5 × 742mm, 2mm bleed, CMYK file type, high-resolution PDF format and outlined vector text for upscaling. Treat those figures as media-owner guidance for that format, not as a universal rule for every 4 sheet print job.

You can use the existing Aspect Printing 4 sheet poster template as a visual starting point, then confirm the exact finished size, bleed and frame requirement before sending final artwork.

Material Choices

The right material depends on where the poster will be displayed. Blueback paper is often used for outdoor advertising because it helps reduce show-through when posters are pasted over older campaigns. For indoor short-term display, standard poster paper may be enough. For more durable signage, rigid boards, PVC banners or laminated large-format prints may be more suitable.

Useful Next Steps

If you know the size you need, start with poster printing, A1 posters or A0 posters. If the poster needs a custom size, special material or outdoor frame compatibility, request a quote and include the frame specification if you have one.

You can send it for checking, but it may need rebuilding because A1 and 4 sheet have different proportions and a large area difference.
