Large-Format Print Guide
QR codes for posters, sized to scan from across the room
A poster is viewed from a distance and lives in varying light conditions. Applying the 1:10 distance formula, mounting at eye level, and exporting print-ready vector SVG turns passersby into active mobile visitors.

Calculate exact poster QR dimensions for any viewing distance
Use our interactive optical calculator to determine the required QR module width based on how far your audience will stand from your poster.

Poster Optical Scan Distance Diagram
For every 1 metre (100 cm) of distance between the reader and the mounted poster, increase the QR code matrix width by at least 10 cm. Sizing toward the optimal recommendation ensures high scan conversion in dim gallery lighting.
For standard A2/A1 posters, size the QR code between 5 × 5 cm and 15 × 15 cm depending on whether visitors walk right up or scan from hallway distances.

The code should be roughly 1/10th the distance it's read from. This size covers the scanning distance shown.
Design & Mounting Rules
4 engineering rules for foolproof poster campaigns
Prevent scan failures in crowded halls, dim gallery corridors, and outdoor environments with these print standards.
Mount codes between 1.4m and 1.7m off the floor
Unlike a handheld flyer, a poster is viewed from a fixed standing position. Placing codes near the bottom edge makes scanning awkward and causes passersby to walk past without engaging.
Maintain deep dark modules on crisp solid backgrounds
Posters often hang under uneven ambient gallery spotlights or outdoor shadow lines. Use pure black or deep navy on solid white containers to guarantee instant camera recognition.
Make your call to action readable from 2 metres away
Passersby decide whether to pull out their phone before they reach your poster. Surround the code with bold microcopy such as 'Scan to Explore Exhibition' or 'Scan for Festival Lineup'.
Apply matte protective laminate for outdoor durability
Outdoor street posters face rain, sunlight fading, and street dirt. Matte lamination prevents glare reflections while protecting ink contrast across multi-week campaigns.
Real-World Applications
Where high-impact poster QR codes drive action
Explore how galleries, festivals, exhibitors, and retailers capture foot traffic from mounted posters.
Art Galleries & Museum Exhibitions
Display elegant framed exhibition posters in entrance foyers, allowing patrons to stream artist audio guides and browse virtual catalogs instantly.
Concerts, Festivals & Street Tours
Wheatpaste street posters across high-footfall urban districts with high-contrast QR codes pointing to live ticket checkout portals and artist playlists.
Trade Shows & Conference Boasts
Eliminate heavy printed catalogs by mounting large-format banner posters that deliver interactive product demos and lead capture forms directly to mobile devices.
Retail Shopfront Windows
Turn dark storefront glass into an active sales channel after closing time with street-facing window posters linking to new collection drops and discounts.
Real Estate & Architecture Previews
Erect site posters outside new developments enabling prospective buyers to scan from the sidewalk and explore architectural renderings and pricing tables.
Campus & Community Noticeboards
Post community announcements across student unions and libraries linking directly to registration forms, map directions, and club calendars.
Post-Print Agility
Update poster destinations after printing 500+ large-format copies
Large-format posters are expensive to print and mount. If an exhibition date changes, a URL has a typo, or a campaign offer expires, a dynamic QR code lets you redirect the traffic in real time without reprinting.

The printed code is identical on both days. Only the destination changed: edited once in the dashboard, no reprint.
Deployment Workflow
4 steps to launch high-converting poster campaigns
From sizing and vector SVG export to eye-level mounting and live analytics.
Calculate Scan Distance
Determine whether your poster will be viewed at arm length (30 cm), across a hallway (100 cm), or from a sidewalk (200 cm) and size the code to the 1:10 ratio.
Brand & Add Scannable Frame
Select high-contrast colors, embed your brand emblem, and wrap the code with an actionable frame such as 'Scan for Exhibition Audio Guide'.
Export Lossless Vector SVG
Download high-precision vector SVG or 300+ DPI PDF files that scale infinitely without pixelation on large A0 or A1 commercial print presses.
Mount at Eye Level & Track Scans
Mount between 1.4m and 1.7m off the ground and monitor real-time scan volume, device operating systems, and hourly engagement peaks in your dashboard.
