Buying Guide
- Window size and placement: Ensure the window center aligns with your most important content. A 7 x 9.75 inch viewing area is common for 9×12 envelopes and typically suits standard photos and certificates.
- Paper weight and durability: Heavier stock (e.g., 28lb or higher) tends to resist tearing and creasing when mailed, especially with glossy prints.
- Adhesive quality: Moistenable glues are common, but consider envelopes with reliable seals if you mail large quantities or have high handling.
- Quantity planning: Bulk packs reduce per-unit cost, but ensure you have storage space and consistent usage to avoid waste.
- Customizability: If you plan to brand or label envelopes, choose printable or label-ready options to streamline address preparation.
- Compatibility with printers: Some window envelopes are printer-friendly; if you address by printer, verify compatibility with your model.
