A3 print on demand, the upgrade.
A3 (29.7 × 42.0 cm) is the most-listed upgrade size in the Etsy poster category. It turns "nice add-on" into "centrepiece" without jumping into the price bracket where customers hesitate. Sellers who add A3 as a second option to an A4 listing typically lift average order value by 25–40%.
A3 — 29.7 × 42.0 cm · £4.10 per print · no setup fees, no minimums.

Product details & specifications
Paper
Museum-quality 270 gsm satin art paper with a soft sheen. Heavy enough to feel substantial when handled, archival enough to last decades without yellowing or fading. The same paper used on every size in our catalogue.
Inks & press
Pigment-printed on a 12-colour press for exceptional colour range and archival permanence. Pigment ink (not dye) means colours hold their depth for 60+ years under normal indoor display conditions.
Packaging
Sizes A4 and larger ship rolled in plain unmarked tubes. A5 and smaller ship flat in stiffened mailers. Every order goes out unbranded — no Zela Print logos, no packing slips, no invoices. The customer only sees your brand.
Dispatch & shipping
Most orders dispatched within 48 working hours. UK arrives 1–3 working days, EU 3–6, rest of world 5–10. Every parcel is tracked end-to-end — the tracking number goes back to you so you can update your customer in your own voice.
Order minimums
None. Order one print or a hundred — same care, same standard, same paper. No setup fees, no contracts, no quotas.
File requirements
JPG, PNG, TIFF, or PDF up to 100 MB. Aim for 300 DPI at your chosen size — for example, 3508 × 4961 pixels for A3 or 7200 × 10800 for 24×36 inch. The configurator checks your file at upload and warns if resolution is too low to print sharp.
Damage & reprint guarantee
Every order is covered by the Zela Print guarantee. If a print arrives damaged in transit, or faded, or with a colour defect, send a photo within 21 days and we reprint and re-ship free of charge — direct to your customer.

Where A3 works.
Centrepiece wall art
A3 hits the sweet spot for a single print on a living-room or bedroom wall — visible from across the room, not overwhelming.
Gallery wall anchor
Use one A3 print as the focal point with smaller A4 and A5 prints around it. Sells brilliantly as a bundle.
Concert and band posters
A3 is the traditional band-poster format. Detail at this size feels deliberate, not stretched.
Printed on 270 gsm satin art paper with archival pigment ink. The satin sheen brings out depth in darker designs without the glare you get from gloss paper.
Standard high-street frame size — IKEA, Habitat, John Lewis, every framer. Ships rolled in a plain unmarked tube; flat-mailer not available at A3.
Common A3 questions.
Is A3 worth offering as an upgrade option?
Almost always. Most poster sellers see A3 outsell A4 once both are listed — buyers default to the size that feels more like a real print. The margin is also better.
How sharp does my file need to be for A3?
For best results: 3508 × 4961 pixels (300 DPI). We'll print anything from 200 DPI upwards but will flag low-resolution uploads before you confirm.
