About stampulator

This page calculates how many 1st/2nd class stamps you need for large letters and parcels.

Read my blog about why I created this here. When Royal Mail prices change please prompt me (email via my blog or twitter message to @srooteu) and I'll update the calculations. thanks!

Can you help please?

Stampulator is free. If you want to say thank you it would mean a lot to me if you would donate to my 2022 Expedition W3W challenge where I climb a mountain and ALL of your donations get split between 3 great charities. You can see a video of me explaining how the challange camea about at https://www.roots.uk/expedition-w3w

Printable page

I designed this page to be printable. It makes for a very long poster, useful for quick reference.

Which stamps do you have?

By default, it's assumed you have the standard UK 1st (95p), 2nd (68p), Large 1st (£1.45p) and Large 2nd (£1.05p) which are are the April 2022 prices from Royal Mail (link also includes size and weight limits). Alternatively, enter the values of the stamps you have here and press submit. If you don't need all 4 values use a high number like 9999 so it won't be suggested in the calculation. If you'd like a page for a different country or values comment on my blog and I'll see what I can do.
