6×9 Booklet

6×9 booklet envelopes are a versatile and practical choice for various mailing purposes. Measuring 6″ by 9″ (152.4mm by 228.6mm), they offer a spacious area ideal for holding multiple pages without folding, or larger documents that can be folded once.

Unlike standard commercial envelopes, 6×9 booklet envelopes typically have the flap on the longer side, making them more convenient for inserting booklets, catalogs, brochures, and other multi-page documents. This design facilitates easy filling and handling, especially for bulk mailing.
