Key Considerations Beyond Flyer and Leaflet Sizes
Beyond leaflet sizes and A5 leaflet design, paper stock and folding influence how your leaflet campaign is received.
Paper weight: Standard flyers and leaflets use 130–170gsm gloss or silk, while high-impact leaflets (like A3 leaflet or A7 leaflet) may use 200–300gsm for a sturdy feel.
Folding: Tri-folds are common for DL leaflet or A4 flyer designs. Bi-fold and z-fold formats let you expand information without overwhelming the layout, ideal for complex leaflet campaign needs.
Leaflet Distribution Prices, Campaign Planning, and Cost Efficiency
Leaflet distribution prices depend on size, weight, and print volume. A5 and A6 flyers offer budget-friendly routes for mass handouts, while A7 printing is the ultimate choice for cost-per-unit savings. DL leaflet formats are often used for targeted mail drops, where precise leaflet campaign management is crucial.
For large print and distribution runs, consider bundling sizes, such as pairing A5 printing for main promos and A7 flyers as add-on offers.
Conclusion: Choosing the Best Leaflet Size for Your Leaflet Campaign
