The number of stamps needed for an envelope depends on the weight and destination. The weight limit for a standard USPS First-Class Mail envelope is 3.5 ounces. For an envelope weighing 12 lbs, you would need to use a different shipping method, such as USPS Priority Mail or USPS Priority Mail Express. The specific number of stamps required can be calculated using the USPS postage rate calculator or by visiting your local post office.
It is a combination of size and weight. The size will require an additional fee as it is classified as over-sized and doesn't get handled by machines. You will have to weight you envelope, which you can do at the post office.
