Letterbox-sized items
Slim books, documents and accessories can use postable services when they stay within the courier’s exact size and weight limits.
Send small, lightweight and letterbox-sized parcels without paying for more delivery than you need. Compare low-cost collection, drop-off, economy and next day services from trusted couriers for UK and international delivery.
Prices, size limits and service availability depend on the packed dimensions, weight, route, courier and delivery option selected.
A small parcel can be inexpensive to send when its finished size and weight fit the right courier service. Interparcel compares low-cost options for letterbox-sized packets, lightweight items and compact boxes so you do not have to rely on one carrier.
Small parcel delivery can cover far more than envelopes. Books, clothing, accessories, spare parts, gifts and compact eCommerce orders can all qualify for cheaper or specialist services depending on their packed dimensions.
If your item is genuinely letterbox-sized, postable services can be especially economical. If it is a little larger, compare standard small-box services as well so you do not pay for speed or capacity you do not need.
Compare small parcel pricesSlim books, documents and accessories can use postable services when they stay within the courier’s exact size and weight limits.
Gifts, parts, clothing and everyday goods can stay inexpensive when the outer box is strong, compact and accurately measured.
Small customer orders, samples and returns are ideal for comparing economy, drop-off and postable services instead of defaulting to next day.
Small does not always mean slow. Compare postable next day, small-pack and express services when a compact shipment needs to arrive quickly.
Compare a mix of low-cost, postable, drop-off and next day services for small and lightweight parcels. The best option depends on the finished parcel dimensions, weight, route and how quickly it needs to arrive.
There is no universal small-parcel size used by every courier. The most useful approach is to measure the finished package and compare the services whose limits it actually fits.
Evri ParcelShop Postable currently accepts parcels up to 1kg and 35cm x 23cm x 2.5cm, making it useful for compact, low-value items that can fit through a standard letterbox.
APC Mail Pack is designed for documents and small packages up to 1kg. The courier supplies an APC bag at collection, and the service is aimed at compact next-day shipments.
APC Courier Pack is designed for small packages up to 5kg, giving heavier compact items a next-day collection option without moving straight to a larger parcel service.
A parcel that is “small” for one network may be standard size for another. Enter the exact packed weight and dimensions so the quote only shows services that can accept it.
The packed shape matters as much as the weight. A slim 500g packet may qualify for a postable service, while a 500g cube needs a standard small-parcel service.
Best for flat, lightweight items that fit the courier’s strict thickness limit.
Best when the item needs more depth, cushioning or a rigid outer carton.
Not sure which fits? Enter the finished dimensions and weight once and the quote will only show compatible services.
Small parcels are easy to underestimate. Pack the item first and then measure the finished package so the comparison reflects the parcel the courier will actually handle.
Do not guess the parcel size A few extra centimetres of packaging can move a parcel out of a postable or small-pack service, so measure after sealing.
Choose packaging that is strong enough for the contents without making the parcel unnecessarily large.
Record the finished weight, length, width and height after the parcel has been sealed.
Review postable, economy, collection, drop-off and next day options that fit the shipment.
Balance price, speed, handover method, tracking and any transit cover shown with the service.
Complete the booking, follow the label or QR instructions and track the parcel online after handover.
Keep the parcel compact without sacrificing protection. These four checks help reduce wasted space and keep the finished shipment suitable for lower-cost small-parcel services.
Use the smallest strong box or mailer that comfortably fits the item and protection.
Add cushioning only where needed so the contents cannot slide, rattle or strike the outer walls.
Use strong parcel tape across the main seam and exposed openings, with the label flat on top.
Record the final weight, length, width and height - not the dimensions of the unpacked item.
Several low-cost UK drop-off services offer QR code or Print In Store options, which can make sending a small parcel easier when you do not have a printer at home.
Printer requirements vary by courier and service. International parcels may also need printed customs documents, so check the booking instructions before travelling to the drop-off point.
Compare no-printer deliveryLook for printer-free, printer-optional or Print In Store information when you compare the available courier options.
Use the code supplied for the selected service and compatible shop, locker or service point.
Produce the label at the correct location, attach it securely to the parcel and complete the handover.
