This collection is sized to fit the Royal Mail Small Parcel format, maximum 450 x 350 x 160mm, giving you more depth than a large letter while staying on the lower parcel rate. Parcelsend stocks these boxes and mailers in the UK for same-day despatch. If your item is flatter, check our Royal Mail Large Letter sized packaging instead.
How to choose the right Small Parcel packaging
Royal Mail Small Parcel allows up to 450 x 350 x 160mm once packed and sealed, so this format suits boxed items with a bit more bulk than a letter or padded mailer can hold.
Boxed items with depth
Small retail products, multiple items bundled together, or anything that needs a rigid box rather than a flexible mailer will typically fall into this size band.
Staying within the size limit
Measure the outside of your box once it's packed and taped, as the 160mm depth limit applies to the finished parcel, not the flat-packed box.
