Blog - PiP Postal Guide - Box Sizes and Prices 2024
The parcel and letter sizing system includes four main categories: Letters, Large Letters, Small Parcels, and Medium Parcels, each with specific dimensions and thickness limits that determine postage costs. For instance, 'Letters' must be within 240 mm x 165 mm x 5 mm, with a maximum weight of 100g, and 'Large Letters' can go up to 353 mm x 250 mm x 25 mm, with a maximum weight of 750g. 'Small Parcels' and 'Medium Parcels' have larger dimensions, respectively, as you can see in our size chart.
By staying within these limits, businesses can avoid higher postage fees and optimise their shipping expenses. The PiP system encourages more efficient packaging and mailing practices, helping businesses predict and manage their mailing costs more effectively.
Additionally, optimising PiP box sizes can lead to reduced material usage and lower shipping costs, making operations more efficient. Streamlined packaging dimensions can also enhance the customer unboxing experience, projecting a professional image and potentially increasing customer satisfaction and loyalty.
- When choosing packaging, first measure the dimensions of your products. Then refer to the detailed PiP size charts to identify which category provides the closest fit without exceeding the maximum sizes. Opt for rigid boxes or poly mailers made of durable materials that will protect your items during transit.
- Pay close attention to not just length and width, but also the max. thickness allowed for each PiP category. Using packaging that causes your shipment to exceed these limits can incur surcharges.
- It’s important to also consider internal dimensions if using boxes. Ensure there is enough interior space for your products plus any necessary cushioning material. Having to overstuff boxes to fit items can cause them to become oversized.
- By carefully selecting packaging materials sized for a precise fit to your products' dimensions, you can maximise savings while complying with PiP guidelines. Proper sizing also reduces excess packaging waste.
