Thickness of large letter

[collectamanics]

I tried posting a large letter today which measured 2.3 cm thick. Label printing for royal mail says a large letter is 2.5 cm thick. This is not the case as it wouldnt fit through the post office measurements thing. It was 3 milameters to big. So I'm having to post my item as a small parcel. Has anyone else had this problem?

you must have mis-measured your package,

the post office 'slot' is 2.5cm thick,

a large letter cannot be more than 2.5 cm thick, 35.3cm long and 25cm wide,

if your package was bigger than this you had to send as a small parcel

well its sorted now, printed a new label off and voided the other one.only thing a can think of is the plastic bag was bunging up stopping it.
