For the printer

Extend the background 2–3 mm (⅛ in) past every edge, keep text and logos 4–5 mm inside the trim, and supply 300 dpi.

In the Twelver chat a flyer is built on an exact canvas with the headline, prices and phone set as real text, and exported as PNG at double density — an 874 × 1240 canvas gives exactly A5 at 300 dpi. Larger formats are in poster sizes.
