According to the United States Postal Service (USPS), the standard postcard size for a regular postcard is:
* Length: 3.5 inches (8.9 cm)
* Width: 5.0 inches (12.7 cm)
This size is also commonly referred to as a "regular" or "standard" postcard.
Here are some additional specifications from the USPS:
* Postcards must be at least 3.5 inches long and 5.0 inches wide.
* The maximum thickness for a postcard is 0.016 inch (0.406 mm).
* The weight of a postcard, including the card itself and any enclosures, cannot exceed 1 ounce (28.35 grams).
Keep in mind that these specifications apply to regular postcards, which are intended for one-way communication. If you're looking to send a larger or thicker item, such as a greeting card or a folded design, you may need to use a different type of mailpiece or consult with the USPS for specific guidelines.
I hope that helps!
The standard postcard size in inches is:

This size is commonly referred to as a "standard" or "regular" postcard, and it's the most widely accepted format for postcards.
However, it's worth noting that there are other standard sizes for postcards, including:
* Jumbo Postcard: 4.25 inches (10.8 cm) x 6.0 inches (15.2 cm)
* Large Postcard: 3.75 inches (9.5 cm) x 5.75 inches (14.6 cm)

But the standard size of 3.5 inches x 5.0 inches is by far the most common and widely used.
The standard postcard size in centimeters (cm) is:

This is the typical size of a postcard that can be mailed internationally, and it's widely accepted by postal services around the world.
A postcard-sized image is typically considered to be 4 inches by 6 inches (10.2 cm x 15.2 cm) in physical dimensions.
To convert this to pixels, we need to consider the resolution of the screen or device on which the image will be displayed. A common resolution for a postcard-sized image is:
* For a standard definition display (e.g., a mobile phone): approximately 640x960 pixels
* For a high-definition display (e.g., a tablet or desktop computer): approximately 1280x1920 pixels
Keep in mind that these are rough estimates, and the actual pixel size may vary depending on the specific device and its screen resolution.
Here's a summary:
| Resolution | Pixel Dimensions |
| --- | --- |
| Standard Definition (SD) | 640x960 |
| High-Definition (HD) | 1280x1920 |
Remember that these are just rough estimates, and you should consider the specific requirements of your project or device when designing an image for a postcard-sized format.
