Quick Answer

What pixel dimensions for A1 at 300 DPI?

7016 x 9933 pixels (594 x 841 mm / 23.39 x 33.11 inches). A1 is the largest ISO A-series size in the pack — twice A2, four times A3. Part of the ISO A-Series pack.

What Is A1 Print Size?

A1 measures 594×841 mm (23.39×33.11 inches). It's the largest ISO format in the SnapToSize pack — exactly double A2 in area, four times A3, and a true statement piece for living rooms, offices, and gallery exhibitions.

Like every A-series size, A1 uses the 1:1.414 aspect ratio (the square root of 2). Fold an A1 in half and you get an A2. Fold that A2 in half and you get an A3. Your artwork composition scales perfectly across the entire series without cropping — learn more about how this works in the Etsy print ratios guide.

For Etsy sellers, A1 anchors the top of the ISO size range. It's the poster-sized format that international buyers search for when they want oversized wall art — the equivalent of a 24×36 in the US market. For a full overview of every Etsy size, see the complete Etsy print sizes guide.

A1 Pixel Dimensions at 300 DPI

Print Size594 × 841 mm (23.39 × 33.11 in)
Pixel Dimensions7016 × 9933 px
Resolution300 DPI
OrientationPortrait (taller than wide)
Aspect RatioISO A-series (1:1.414)

The math: convert millimeters to inches (divide by 25.4), then multiply by 300. Width: 594 ÷ 25.4 × 300 = 7016 pixels. Height: 841 ÷ 25.4 × 300 = 9933 pixels.

Always create your A1 files at 300 DPI. Deliver as JPG (also called JPEG) — this is the professional print standard and what buyers expect from Etsy digital downloads. Your source image must be at least 7016×9933 pixels — anything smaller will produce a blurry print at A1 size. For more on why resolution matters, see best resolution for Etsy printables.

Why Offer A1 on Etsy?

A1 is the largest ISO size in the pack and the format that attracts premium, international orders. Here's why it belongs in your listings:

A1 is the oversized poster format in metric countries

In the UK, EU, Australia, and New Zealand, A1 is the go-to size for large statement posters. It fills the same role as 24×36 does in the US — but with different dimensions and the ISO 1:1.414 aspect ratio.

Premium positioning = higher revenue per sale

A1 is an investment piece. Buyers who want A1 are decorating living rooms, offices, and galleries — not looking for a small desk print. This means higher price points and buyers with larger budgets, especially for gallery wall sets where A1 serves as the centerpiece.

Active demand on Etsy

Etsy has dedicated marketplace categories for A1 poster art, and buyers actively search for “A1 poster” and “A1 print.” Including A1 in your listing eliminates “do you have A1?” messages and captures sales you would otherwise miss. For guidance on how many sizes to include, see how many sizes to offer for Etsy printables.

The cost of adding A1 is essentially zero. Since all A-series sizes share the same ratio, one master design produces A5, A4, A3, A2, and A1 with simple scaling. You're reaching millions of international buyers with minutes of extra work per listing.

A1 vs 24×36 — Size Comparison

A1 is the closest ISO equivalent to the US 24×36 poster size, but they are not interchangeable. Here's how they compare:

 A1 (ISO)24×36 (US)
Dimensions (in)23.39 × 33.1124 × 36
Dimensions (mm)594 × 841610 × 914
Pixels @ 300 DPI7016 × 99337200 × 10800
Aspect Ratio1:1.414 (ISO)2:3
Primary MarketUK, EU, Australia, NZUS, Canada

A1 is 0.61 inches narrower and 2.89 inches shorter than 24×36. More importantly, they have different aspect ratios — you cannot resize one to the other without cropping or adding white space. An A1 design printed at 24×36 proportions will look noticeably different.

For Etsy sellers, the practical answer is to offer both. International buyers search for “A1 poster” while US buyers search for “24×36 poster.” Including both in your listing covers both markets — each ratio family needs its own version, and SnapToSize generates them all from a single upload.

How to Frame A1 Prints

A1 frames are less common at retail stores than A3 or A4 frames. Including framing guidance in your Etsy listing reduces buyer confusion and support requests. Here is what your A1 buyers need to know:

Exact frame size594 × 841 mm (23.39 × 33.11 in)
IKEA optionLOMVIKEN A1 frame (market dependent)
Clip framesWidely available & affordable for A1
Online searchAmazon “A1 poster frame” or “594×841mm frame”
Mat optionsUncommon — most A1 prints displayed unmatted

In Europe, the UK, and Australia, A1 frames are available at most frame shops and online retailers. In the US, A1 frames are harder to find at big-box stores but readily available on Amazon and through custom framing services. Clip frames are the most affordable and widely available option for A1.

Copy this into your listing: “This A1 file prints at 594×841 mm (23.39×33.11 inches). A1 frames are available at IKEA (LOMVIKEN, market dependent), Amazon (search ‘A1 poster frame’ or ‘594×841mm frame’), and most European frame shops. Clip frames are an affordable alternative for A1 posters.”

A1 in the ISO A-Series — The Complete Scaling Chain

Every A-series size is exactly half the next size up. A1 is the anchor — the largest size in the pack. One design scales across the entire family without cropping because they all share the 1:1.414 ratio:

SizeDimensions (mm)Pixels @ 300 DPIRelation to A1
A1This Page594 × 8417016 × 9933Full size (1×)
A2420 × 5944961 × 7016Half A1 (2× smaller)
A3297 × 4203508 × 4961Quarter A1 (4× smaller)
A4210 × 2972480 × 3508Eighth A1 (8× smaller)
A5148 × 2101748 × 2480Sixteenth A1 (16× smaller)

All five sizes share the same 1:1.414 aspect ratio. Design at A1 resolution (7016×9933 pixels) and scale down to A2, A3, A4, and A5 without any cropping or distortion. This is the most efficient way to reach international buyers alongside your US sizes.

A1 is the ceiling of the pack — the biggest format your buyers can print. Sellers who include A1 in their listings signal professionalism and attract buyers looking for premium, oversized wall art.

How to Create A1 Files for Etsy

1. Design at 7016×9933 Pixels or Larger

A1 requires a source file of at least 7016×9933 pixels at 300 DPI. Since A1 is the largest ISO size in the pack, designing at this resolution means every smaller A-series size (A2, A3, A4, A5) will scale down perfectly. Going the other direction — upscaling an A2 or A3 file to A1 — will make the image look soft or pixelated.

2. Export as JPG at 300 DPI

JPG (also called JPEG) maintains full print quality while keeping files well under Etsy's 20 MB upload limit. Even at A1 resolution, a well-optimized JPG stays manageable. PDF is an alternative for text-heavy printables.

3. Generate All Sizes from One Upload

Manually creating A5, A4, A3, A2, and A1 versions — plus US sizes like 24×36, 18×24, and 8×10 — takes hours per artwork. The alternative is a tool that handles all sizing automatically from one high-resolution source file. For a walkthrough, see how to resize images for Etsy.

Skip the manual work: SnapToSize generates A1 alongside A2, A3, A4, A5, and all US sizes from one upload — at 300 DPI, professionally named, organized in ZIP packs, and under Etsy's 20 MB limit.
