Ever thought about sending a piece of your creativity through the mail? Homemade postcards are a unique and personal way to connect with friends, family, or even pen pals. But can you mail homemade postcards? The answer is yes, with a few considerations to ensure they reach their destination safely and legally.
Understanding Postcard Regulations
Before you start crafting your masterpieces, it's essential to understand the regulations surrounding postcards. The United States Postal Service (USPS) has specific guidelines to ensure the safety and efficiency of mail delivery.
Size and Weight
Postcards must be at least 3.5 inches high and 5 inches long, and no more than 4.25 inches high and 6 inches long. They must also be at least 0.007 inches thick and no more than 0.016 inches thick. The weight limit for a postcard is 1 ounce.

Material
Postcards can be made from a variety of materials, but they must be flexible and able to pass through sorting machines. This means no rigid materials like wood or metal. Cardstock, paper, and lightweight cardboard are all suitable options.
Preparing Your Homemade Postcards
Once you've got your materials and understand the regulations, it's time to start creating your postcards. Here are some tips to ensure your postcards are mail-ready:
- Use Lightweight Materials: As mentioned earlier, your postcard must be flexible and lightweight to pass through sorting machines.
- Leave Space for Address and Stamp: Make sure to leave enough space on the front of your postcard for the address and stamp. The USPS recommends leaving at least 1/2 inch on the bottom for the address and 1 inch on the top for the stamp.
- Consider the Design: If you're using ink or paint, make sure it's dry before sending your postcard. Also, consider using waterproof materials if you're worried about your design smudging in the mail.
Addressing and Stamping Your Postcards
Once your postcards are complete, it's time to address and stamp them. Here are some tips:
- Addressing: Write the address clearly and legibly. Use a pen or pencil, and make sure the ink doesn't bleed through to the other side. Also, consider using a return address in case your postcard gets lost.
- Stamping: The postage for a postcard is currently 0.40 for domestic use. You can purchase stamps at your local post office or online. If you're unsure about the postage, you can use a postage meter or ask a postal worker to help you.
Special Considerations
While most homemade postcards can be mailed without issue, there are a few special considerations to keep in mind:
Prohibited Content
The USPS prohibits mailing certain types of content, including dangerous or illegal materials, copyrighted materials without permission, and obscene or indecent materials. Make sure your postcards comply with all postal regulations.
International Mail
If you're sending your postcard internationally, you'll need to follow the regulations of the destination country. Some countries have different size, weight, and content restrictions. You may also need to use a different type of stamp or add additional postage.

If you're planning on sending a large number of postcards, you might want to consider using a postcard service. These services can help you with addressing, stamping, and even delivery. They can also provide you with more information about international mail.
