St. Patrick's Day brings bars, parade organizers and charity runs their biggest crowds of the year, and each leans on a different kind of QR code: a table tent linking to drink specials, a flyer linking to the parade route, a poster linking to a fun run's registration form, or clue cards for a pub crawl. Each is a plain link, encoded once and printed at the size the object needs.
Bars with specials that change through the day get more from a dynamic code, since the table tent stays the same while the destination updates behind it. A parade route or a one-off registration, set once, works fine as a free static code.
Building the code for the day's event
Choose the destination
A drinks menu, a shared map of the parade route, a registration form for a run, or a clue page for a scavenger hunt.
Get the link
A menu page's own address, a shared-map link from a mapping tool, or a form's share link.
Paste it in and preview
Check the preview opens the right page on your own phone before the flyers or table tents go to print.
Print at the right size for where it hangs
Small for a table or wristband, much larger for a flyer taped to a pole along the parade route.
Bars: a code that can change with the taps
Drink specials that rotate through the afternoon are the clearest case for a dynamic code: the same printed table tent stays out all day while the linked menu page updates behind it, so nothing needs reprinting between the lunch and evening specials.
Parade day: a route people can actually follow
A shared map link, built once with a mapping tool and posted as a code on flyers or a printed program, saves parade-goers from squinting at a paper map in a crowd. The code just needs the map's own share link.
Pub crawls and scavenger hunts, one clue at a time
A pub crawl works well as a sequence of separate codes, each printed at one stop and linking to a page revealing the next location. Since each clue is fixed once the route is set, static codes are enough for the whole trail.
What the code contains
A single link: to a menu, a shared map, a registration form or a clue page, depending on the job. No drink prices, route details or entry data live inside the code itself.
https://maps.app.goo.gl/yourparaderouteSizes for tables, flyers and clue cards
A bar table tent scans well at 30 to 40 mm from a seated guest's distance. A parade flyer posted on a pole, read from a few meters away, needs 15 cm or more. A pub crawl clue card handed to someone up close works at 25 mm.
Print it at least 25 mm (2.5 cm) wide
What trips up a St. Patrick's Day code
A static code for rotating specials
Specials that change through the day need a dynamic code, or the printed table tent quickly shows the wrong menu.
A map link with the wrong route saved
Double-check the shared map link opens the current year's route before flyers go out; routes sometimes shift year to year.
Too small on a wristband
A wristband gives little room; keep the code above the 20 mm minimum rather than shrinking it to fit, or move it to a card instead.
Static or dynamic for the day's signage?
A bar with specials that rotate benefits from a dynamic code, repointed as the menu changes without a new print run. A one-off parade map, charity run sign-up or pub crawl clue trail is fixed once it's set, so a free static code covers it.
How dynamic QR codes workWhere this code shows up on the day
- A bar table tent linking to the current drink specials.
- A parade flyer linking to a shared route map.
- A charity fun run poster linking to online registration.
- A pub crawl clue card revealing the next stop.
