The recent changes to how the Royal Mail charges for delivery of letters is actually quite simple, now that I’ve got used to it.
Letters are now separated into three bands:
240 x 165 mm (x 5mm max. thickness)
max weight: 100g
- Large Letter
353 x 250 mm (x 25mm max. thickness)
max weight: 750g
> 353mm long or > 250mm wide (or > 25mm thickness)
max weight: depends on service
Which is why I laughed when I received an envelope (pictured above) from my sister Jenni.
This small envelope is only 150mm x 90mm (6″ x 3.5″) and yet has a “Large Letter” stamp on it. I wonder what the smallest large letter I could send would be.
