An A1 poster measures 23.4 x 33.1 inches (594 x 841 mm). To get a clean fit, look for a frame labeled “A1” or one that lists those exact dimensions.

• No mat: Choose an A1 frame so the poster fills the opening.
• With a mat: Use a larger frame and a mat cut to A1. This creates a border and helps center smaller prints.
• Check the opening: Frame dimensions can refer to the insert size, not the visible area. A slight lip will cover a few millimeters.

These tips can help you match your poster and frame more precisely, but dimensions and fit can vary by design.

“A1” is part of the ISO paper size system. An A1 frame is designed for artwork that’s 23.4 x 33.1 inches (594 x 841 mm). On product pages, you might see it listed as “A1” or by those exact measurements.

• Fit intent: The insert area is made to hold A1 posters or prints.
• With mats: Some frames include mats sized for smaller formats, which reduces the visible opening.
• Listings vary: Dimensions may describe the insert size, not the glass’s full viewable area.

If you’re unsure, measure your print and compare it to the frame’s stated insert size for the most reliable match.

No—50 x 70 cm is smaller than A1. A1 measures 59.4 x 84.1 cm (23.4 x 33.1 inches), so an A1 poster won’t fit into a 50 x 70 cm frame.

• For A1 posters: Choose a frame labeled A1 (or 594 x 841 mm). If you prefer a mat, use a larger frame with a mat cut to A1.
• For 50 x 70 cm posters: Pick a frame listed as 50 x 70 cm, or step up to a larger size and add a mat.

Checking your print’s exact measurements against the frame’s insert size can help avoid gaps or trimming.

Both materials can work well for large A1 frames, and the best choice depends on your priorities.

• Acrylic (plexi): Lighter and shatter-resistant, which can make hanging large frames easier. It may scratch more easily and can carry static, but options with UV or anti-glare features are available.
• Glass: Generally more scratch-resistant and can offer a crisp, clear look. It’s heavier and can break if dropped; some frames use tempered or specialty glass to address those concerns.

Consider where the frame will hang (traffic, weight support, light exposure) and review the product details to find the glazing that aligns with your needs.

Large frames can be secure and level with a few simple steps.

• Check hardware: Many frames include pre-installed hangers for vertical or horizontal display. Confirm the frame’s weight and hanger type.
• Use two hooks: Two wall points can improve leveling and stability.
• Match anchors to your wall: Choose hardware suitable for drywall, plaster, or masonry. Following the hardware’s weight rating is advisable.
• Mind placement: Avoid moisture-prone spots and prolonged direct sunlight, which can affect prints over time.

Following the included instructions and using appropriate anchors can help create a secure setup, but results may vary depending on your wall and hardware.
