printed postal boxes

printed postal boxes are postal cartons printed with a seller logo, colours and messages so a parcel promotes the brand while it travels. Custom Postal Boxes manufactures its printed postal boxes product range in Wolverhampton, with sizes covering flat letterbox goods through to fuller small and medium parcels for UK dispatch.

Choosing printed postal boxes by size first

Size decides cost, protection and whether a parcel can go through a letterbox, so settle it before artwork. Work through the postal boxes by size collection with your products in front of you, measuring each one as packed. Flat goods such as prints, books and documents may fit a large letter format at up to 353mm by 250mm by 25mm and 750g, while boxed gifts, footwear and bundles move into small parcel at up to 450mm by 350mm by 160mm and 2kg under Royal Mail definitions.

Keep the size family small. Two or three printed sizes that genuinely fit the range will be reordered more often, stored more neatly and recognised more strongly than a cupboard full of near duplicates. Seasonal artwork can change on the same proven sizes, giving returning customers something fresh to notice without forcing packers to learn a new box every few months or leaving part used stock behind.

Letterbox printed boxes and the convenience effect

A printed box that fits through the letterbox removes the missed delivery card from the customer experience. The parcel is inside, dry and waiting, and the branding is the first thing seen on the mat rather than on a doorstep or at a collection point. For slim repeat purchases such as refills, media and flat gifts, that convenience can matter as much to loyalty as the print itself.

When a parcel box is the better printed choice

Depth buys protection for anything that should not be compressed. If a product has height, glass, a lid that must not be pressed or several components that sit side by side, choose a parcel format and use the extra room for an insert or wrap. A slightly larger printed box that arrives perfect will always represent the brand better than a tight letterbox box that arrives bent or split.

Board and print character in printed postal boxes

Brown kraft postal boxes printed with a strong single colour design look honest and crafted, and they hide light scuffs from transit gracefully. White board gives a brighter background for full colour artwork, product photography and a retail feel. Think about where the box will be photographed and opened, because a design that suits a kitchen table unboxing may read very differently under bright shop or office lighting.

What to print and what to leave off

Include the logo, a short recognisable line, a web address and any handling note the contents truly need. Leave off dense paragraphs, tiny decorative text and information that changes often, such as prices or dated offers, because printed stock outlives a promotion. If a message will change, put it on an insert card instead and keep the box itself timeless enough to use across several campaigns.

Posting printed postal boxes with confidence

Check finished external dimensions and packed weight against the service you intend to use, using the Royal Mail pages on UK services and sizes as your reference, and place labels on a flat panel where print will not be obscured in a confusing way. A label that covers the logo is not a disaster, but planning a quiet label zone into the design keeps every parcel looking intentional rather than accidental.

FAQs about printed postal boxes

Size, board and label placement come up in almost every printed postal enquiry, so these answers deal with those decisions first.

What sizes do printed postal boxes come in?

They are made in sizes covering letterbox, large letter and parcel formats, chosen around your products as packed. Share your product measurements and a practical size family can be specified for your whole range.

Should I choose kraft or white printed postal boxes?

Choose kraft for a natural look and bold simple print, and white for brighter colour and detailed artwork. Consider where customers will open the parcel and which board shows your brand colours best.

Can printed postal boxes go through a letterbox?

Yes, if the finished box and contents stay within large letter limits and the recipient has a standard letterbox. Measure the packed thickness carefully, because board and contents together decide the fit.

Where should the delivery label go on a printed postal box?

Place it on the largest flat panel, away from seams and tape. Planning a quieter area in the artwork for the label keeps the branding visible and the parcel looking tidy on arrival.

How do I order printed postal boxes for my shop?

Send your sizes, board preference, artwork and quantity through the contact page. Pricing depends on size, material and quantity, with low minimum order quantities and free design support available.
