What affects Royal Mail postage

Format: letter, large letter, or parcel (format impacts pricing tiers).
Weight & size: heavier and bulkier items cost more; precise measurements prevent overpaying.
Distance: UK vs. international destinations and zones influence rates.
Speed & extras: faster services and options like tracking or delivery confirmation can add cost.

Parcel formats explained (quick guide)

UK shipping: multiple delivery-speed options, with tracked services for peace of mind.
International shipping: economy, standard and tracked/signed options, each with different delivery aims.
Customs & forms: for many destinations outside the UK, you’ll need customs details; prepare item descriptions and values before you ship.
