Are these stamps large or ordinary first class?

[noopowders.eu_noopept_phenibut_nsi189]

I have two 1at class stamps, without "large" written on them but looking rather big. Do you know if they are for large letter or small?

I put an ordinary small stamp for comparisson.

Thank you.

They are ordinary 1st class stamps.

They are a large size because they are commemoratives.

The large letter stamps always have Large printed on them and are usually large size definitives (Queens head only)
