How large are Visa and Multiple Reentry stamps in Thailand?

Visa stamps in Thailand typically occupy about 1/2 a page in your passport, while re-entry permits take up a similar amount of space. However, if you opt for a multiple re-entry permit, only one arrival stamp will be made in your passport, utilizing approximately 1/6 of a page. Frequent travelers to Thailand may find themselves running out of passport pages due to the various stamps required. It's worth noting that some countries, like the US, no longer allow adding extra pages to passports, and the recommendation is to renew to a new passport if more pages are needed.
