Royal Mail Postage Size Guide, Easy & Accurate Measurements for 2025
Raven Laser Cut
Why we love it
Accurate sizing eliminates extra fees.
Easy to use for everyone.
Durable design for lasting use.
Main Highlights
ACCURATE SIZING: Ensure precise package measurements with this guide for Mail charges. This template can be used to check three sizes of mail for shipping by UK Mail service. (Small Letters, Large Letters and Small Parcels.)
EASY TO USE: No ruler needed. With this postal size guide you simply pass your items through the relevant space without forcing them through to check thickness and width and then check the maximum length against the marked size on the gauge.
UP-TO-DATE: Complies with current UK Post Office size rules for 2025. It quickly and accurately measures your package’s dimensions, so you don't worry about paying extra fees by being slightly over size.
DURABLE CONSTRUCTION: Sturdy guide for long-lasting use. Made from quality, varnished 6mm thick plywood and is very durable as well as lightweight, making it easy to carry, store and use daily. Ideal for use in a warehouse or for use at home.
ECO FRIENDLY: This is environmentally friendly and made from FSC certified wood. Plastic variants are not great for the environment! Choosing manufacturers that use FSC-certified materials means you're going above and beyond to protect the planet without giving up quality. FSC-certified Wood means it comes from sources where the forest is always regenerated as trees are replanted so there is no net loss of forest.
UK MADE: Manufactured by us in the UK and sealed against moisture with a non-toxic acrylic varnish. The postage size guide is wooden in colour but due to the difference in wood shades the item's colour may be slightly different from shown in the pictures.
IDEAL FOR BUSINESSES: This shipping size guide is an ideal tool for calculation of the exact amount to pay for dispatching the products, by measuring the package dimension accurately for correct postage cost; this ensures the recipient is not getting insufficient postage charges resulting in a poor buying experience.
PERFECT FOR HOME OR BUSINESSES: It is a really essential tool for any business or online seller.
PLEASE NOTE: If ordered before 3pm, we will dispatch the same business day with tracked 24hr service.
