small boxes for posting

small boxes for posting are compact cartons sized to protect smaller products while keeping parcels inside economical Royal Mail size bands, and they can be printed with your branding. Custom Postal Boxes makes small boxes for posting in Wolverhampton in custom sizes, with low minimum order quantities and free design support.

Why small boxes for posting are a smart default

Smaller products posted in oversized boxes cause three avoidable costs. The parcel may fall into a higher postage band, the product moves and risks damage, and extra filling is needed on every order. A box sized closely to the product answers all three. It holds the item steady, uses material efficiently and gives the customer a parcel that feels proportionate to what they bought.

Small boxes also speed up a packing bench. A team packing the same product many times a day benefits from a box that folds quickly, closes securely and needs little judgement about padding. Consistency matters for returns as well, because a customer can reuse a sound small box to send an item back in the same protection it arrived in.

Letterbox, large letter and small parcel sizes

The thinnest small boxes can travel as large letters or through a letterbox, which avoids missed deliveries. Slightly deeper boxes suit the small parcel band. Our small postage boxes, letterbox postal boxes and A5 postal boxes cover the most requested posting formats for smaller goods.

Measuring the packed item, not the product alone

Always measure with the product in its inner wrapping, plus any card, tissue or padding you intend to use. Board thickness adds to the outside measurement that postage is based on. A few millimetres of honesty at the measuring stage prevents a whole batch of boxes tipping into a higher band.

Royal Mail bands that shape small box sizes

Royal Mail prices by size and weight together. A large letter can measure up to 35.3cm by 25cm by 2.5cm, a small parcel up to 45cm by 35cm by 16cm and 2kg, and a medium parcel up to 61cm by 46cm by 46cm. Designing your box to keep a common product inside the lowest workable band is one of the simplest savings an online seller can make. Read the current Royal Mail size and weight guidance before fixing a new size.

Weight deserves the same attention as dimensions. Board grade, inserts and filling all add grams, and a parcel near a weight limit needs a small safety margin for labels and tape. Lighter board that still protects the product is usually the right aim for small, low value items posted in volume.

Materials and print for small posting boxes

Single wall corrugated board and sturdy card cover most small posting needs. Kraft gives a natural look, white board takes bright print, and both can carry your logo, a thank you message or handling guidance. Even a small box has enough panel space for branding that customers recognise, and printed boxes reduce the need for extra stickers and stamps at the packing bench.

Ordering small boxes for posting

Custom Postal Boxes is a project of Vertex Packaging, based in Wolverhampton, and manufactures in house. Orders are quote based, and pricing depends on size, material and quantity. Low minimum order quantities suit sellers testing a new product or a better fitting size, and free UK delivery applies. Share your product dimensions, packed weight and target postal band for the most accurate recommendation.

Start through our contact page for a quote with the items you post most often. If you post several product sizes, list them all, because two well chosen small box sizes often serve a whole shop better than one compromise size that fits nothing quite right.

FAQs about small boxes for posting

What size box counts as a small parcel with Royal Mail?

A Royal Mail small parcel can measure up to 45cm by 35cm by 16cm and weigh up to 2kg. Your packed box, including board thickness, labels and tape, must stay within those limits. Thinner items may qualify as a large letter at up to 35.3cm by 25cm by 2.5cm.

How do I choose the right small box for my product?

Measure the product in its inner wrapping, add a few millimetres of clearance, and check the packed weight. Then match the result to the lowest Royal Mail band it fits. A close fit protects best and usually posts cheapest, so avoid rounding up to a much larger box.

Can small boxes for posting be printed with my logo?

Yes. Small postal boxes can be printed outside and inside with your logo, colours and messages. Free design support helps place artwork away from folds and the label area, so the box looks tidy and the address and barcode stay clear for delivery staff and scanners.

Are small cardboard posting boxes recyclable?

Cardboard posting boxes can usually be recycled with household cardboard once tape and plastic labels are removed. Choosing a close fitting box also reduces the filling needed, which cuts waste further. Customers often reuse a sound box for returns before recycling it.
