Allow for packaging as well as the gift
Price the packed parcel, protect fragile parts and leave room for the label before buying the gift.

The gift is not the parcel
A mug weighs one amount on its own and another once it is safely surrounded by cushioning and a strong box. The finished package is also larger than the object inside it. Before committing to a gift you intend to post, estimate the complete parcel rather than checking postage against the product dimensions. Packaging is part of the plan, not an inconvenient extra discovered afterwards.
Small dense objects can cost more to send than broad light ones, depending on the service. A fragile object may need generous protection that moves it into a larger parcel category. Check the carrier's current size and weight rules for the route you will use. Prices and service limits can change, so an old label or previous shipment is only a rough comparison.
Protect the points that can break
Start with a suitable strong container. A gift box may look finished but lack the construction needed for postal handling. Fragile items should not touch each other or the outer walls directly. Royal Mail's guidance recommends individual cushioning and separating multiple fragile pieces. Follow the carrier's instructions for the contents rather than relying on a “fragile” sticker to change how the parcel travels.
Look for projecting parts: a mug handle, pin post or the corner of a framed piece may need particular protection. Keep hard accessories from knocking against delicate surfaces. Fill unused space appropriately so the contents do not move freely, but do not compress the package until it bulges. The goal is a protected arrangement, not simply the smallest box you can close.
Weigh after sealing
Once the parcel is ready, measure and weigh it again. Tape, protective material and the outer box all count. Accurate figures help you choose the correct service and avoid sending a parcel with insufficient postage. Leave an area large enough for the address label, postage and any required customs documents. Labels should be clear and placed according to the carrier's instructions.
Check the address, postcode and return details before handing the package over. If reusing suitable packaging, remove or fully cover old shipping labels and barcodes as instructed. Do not let an attractive gift wrap obscure the delivery information. For an international parcel, describe the contents accurately and check current restrictions, declarations and possible recipient charges separately.
A compact robust gift can be a sensible choice when the total sending cost is disproportionate. Alternatively, a retailer near the recipient may offer a simpler delivery arrangement. Keep the useful information until arrival and avoid promising an exact date beyond the service's actual terms. Planning the whole parcel gives the gift a better chance of arriving as an enjoyable object instead of a damaged surprise or an unexpected bill.
