Thailand Post size restrictions per service

[RandomSand]

Does anyone have concise information regarding the various postal rates and size restrictions available from Thailand Post.

For example; "Int’l Small Packet-Air" is priced reasonably, as I can see from their website, but what are the size limits ?

( note to self: Int’l Small Packet-Air = พัสดุย่อยทางอากาศ )

There is a postal rate calculator on their website.

As for the actual parcel sizes, I think you would need to go into the Post Office and enquire.

Weight restrictions too in each category.

Anyone know how large a "Small packet" may be?

I'm not in Thailand to be able to enquire in person.

Thanks.
