How Many Stamps for Small Parcel
When sending a small parcel through the post, you need the right amount of postage to ensure it gets delivered without delays or surcharges. The number of stamps needed depends on the weight, size, and service you choose — not just the fact it’s classed as a small parcel.
In the UK, a small parcel must be no larger than 45cm x 35cm x 16cm and weigh up to 2kg. If your item fits within those limits, it qualifies for small parcel pricing. Anything over that will be classed as medium or large, which changes the postage cost significantly.
Using Stamps vs Buying a Label
Technically, you can use stamps to post a small parcel, but it’s not always the best option. You’d need to calculate the full postage cost based on the parcel's weight and class, then match that value using stamps. For example, if First Class small parcel postage costs £4.19 and you use 66p stamps, you'd need at least seven stamps — and still might be under if prices have changed.
Because of this, most people buy a printed label from a Post Office or online via Royal Mail. It ensures accuracy and often includes tracking, which stamps alone do not. Using the wrong number of stamps can result in delays or extra charges to the recipient.
Parcel Size and Weight: Know the Limits
Before adding stamps or buying postage, it’s important to check your parcel’s exact weight. Parcels over 2kg no longer qualify for small parcel rates, and the price will jump. Weigh your item on a kitchen or postal scale, and use a ruler or tape measure to double-check the dimensions.
Even if your parcel is light, if it’s too thick or large, it could be reclassified and cost more to send. These sizing rules are strict, and parcels are often scanned at sorting centres to check if they qualify.
Cost vs Convenience: What's Worth It?
While using stamps might seem simple, it’s rarely the cheapest or most reliable method for sending a small parcel. Pre-paid labels from Royal Mail or courier services come with tracking options and proof of postage, which are useful if the parcel goes missing or is delayed. Buying postage online also sometimes comes with small discounts compared to in-branch prices.
If you do prefer using stamps, it’s best to take your parcel to the Post Office, where they can weigh and price it for you, and sell the exact number of stamps you need for that specific item.
Summary
The number of stamps needed for a small parcel depends on weight, size, and postage class. While you can use stamps, it’s often easier and more reliable to buy a printed postage label. Stamps don't include tracking, and guessing the right amount can cause delivery problems. For accurate, stress-free posting, especially for heavier items, using official labels is the smarter option.
