Large Letter Packaging

Royal Mail large letter size postal boxes, bags and envelopes

Royal Mail large letter size

Royal Mail's large letter size was introduced in 2006 as part of the new Pricing in Proportion (PiP) policy. A large letter’s size can be no larger than 353 x 250 x 25mm (a normal letter can be only up to 240 x 165 x 5mm) with a maximum weight of 750g.

The cost of paying small parcel rates (the next size up from ‘large letter’) can be significantly more. So being able to quickly source postal boxes and envelopes you can be sure are the right size is a great way of controlling your outgoings.

Large letter envelopes

At Davpack, we have a wide variety of large letter envelopes, like corrugated envelopes, white card envelopes, Gold Mail Lite envelopes, and more. Whether you’re sending documents, CDs, or large letters, our large letter envelopes are ideal for whatever you need.

Large letter postal boxes

We also have some excellent durable and reliable large letter packaging, such as brown EconoBook boxes. To securely send objects, you can also pick up EconoBook boxes with an adhesive strip. This closes your package tightly, giving you the confidence that it will be secure in transit.
