Postcard size in cm


Postcard sizes can vary depending on the country or region, but here are some common standard postcard sizes in centimeters:

* Standard postcard (typically used for international mail):
+ Length: 10.5 cm (4.1 inches)
+ Width: 15 cm (5.9 inches)
* Large postcard:
+ Length: 14.8 cm (5.8 inches)
+ Width: 20.3 cm (8 inches)
* Jumbo postcard:
+ Length: 17.7 cm (6.9 inches)
+ Width: 25.4 cm (10 inches)

Keep in mind that these are general guidelines, and some countries may have slightly different standard sizes for postcards. It's always a good idea to check with your local postal service or the recipient's country to confirm their specific requirements.


Post Card size in pixels


For a postcard, the traditional dimensions are:

* Standard: 3.5 inches wide x 5 inches long (89 mm x 127 mm)
* Large: 4.25 inches wide x 6 inches long (108 mm x 152 mm)

In terms of pixels, these dimensions translate to:

* Standard:
+ Width: approximately 450-500 pixels
+ Height: approximately 750-850 pixels
* Large:
+ Width: approximately 550-600 pixels
+ Height: approximately 900-1000 pixels

Keep in mind that these are rough estimates, and the actual pixel dimensions may vary depending on the resolution and aspect ratio of your image. However, this gives you a general idea of what to aim for when designing a postcard-sized image.

For online postcards or digital postcards, it's common to use a square shape with an approximate size of 400-500 pixels per side (e.g., 400x400 pixels). This allows for easy sharing and viewing on various devices.


Postcard size in mm


The standard postcard size varies depending on the country, but here are some common sizes:

* International postcards:
+ Standard A6: 148 x 105 mm (5.83 x 4.13 in)
+ Large format: 162 x 114 mm (6.38 x 4.49 in)
* US Postcard size:
+ Standard: 89 x 140 mm (3.50 x 5.51 in)
+ Large format: 102 x 152 mm (4.02 x 5.98 in)

Keep in mind that these sizes are not absolute and may vary depending on the country's postal service or specific requirements. If you're designing a postcard, it's always best to check with your target audience's country-specific postal regulations to ensure compatibility.

In terms of design considerations:

* For standard A6 postcards, consider using 15-20% margins around the edges to accommodate any trimming or creasing.
* For larger format postcards, you can use slightly smaller margins (10-15%) since there is more real estate available for your design.
* Remember to keep your design elements visually appealing and balanced within the postcard's dimensions.

If you have any specific design requirements or questions, feel free to ask!


4x6 postcard size in cm


A common question!

The standard dimensions for a 4x6 postcard are:

* Width: 10.2 cm (4 inches)
* Height: 15.2 cm (6 inches)

So, to summarize:

* 4x6 postcard size in cm: 10.2 cm x 15.2 cm


USPS postcard size


USPS (United States Postal Service) has specific guidelines for postcard sizes, which are:

* Maximum dimensions: 3.5 inches (8.9 cm) in height and 5 inches (12.7 cm) in length
* Minimum dimensions: 3.25 inches (8.3 cm) in height and 4.25 inches (10.8 cm) in length
* Thickness: Postcards should be no thicker than 0.007 inch (0.18 mm)

These dimensions apply to both standard postcards and greeting cards with an envelope flap.

It's worth noting that while these are the official USPS guidelines, some private companies may have slightly different size requirements for their own purposes.


USPS postcard size rates


USPS (United States Postal Service) offers various rate options for sending postcards, depending on the size and weight of your mailpiece. Here are some key points to keep in mind:

**Standard Postcard Rate:**

* For a standard-sized postcard (3.5 inches by 5 inches or smaller), the USPS charges a flat rate of $0.35 per piece.
* This rate applies to postcards with a rectangular shape and a maximum thickness of 0.016 inches.

**Large Postcard Rate:**

* For larger postcards (larger than 3.5 inches by 5 inches or irregular shapes), the USPS charges a flat rate of $0.50 per piece.
* This rate applies to postcards that don't meet the standard size requirements, such as square or oblong shapes.

**Additional Rates:**

* If your postcard weighs more than 1 ounce (the average weight of a standard postcard), you'll need to add an extra $0.15 for each additional ounce.
* For international mailpieces, there may be additional rates and surcharges depending on the destination country.

**Meters and Calculators:**

* You can use USPS-approved meters or online calculators to determine the correct postage rate for your postcard based on its weight and size.
* These tools are available at usps.com or in-person at a local Post Office.

Keep in mind that these rates are subject to change, so it's always best to check with the USPS website or visit your local Post Office for the most up-to-date information.


How much does a postcard weigh in ounces


A standard postcard, which is typically made of paper or cardboard and measures around 3.5 x 5 inches (8.9 x 12.7 cm), usually weighs very little.

The weight of a postcard can vary depending on the material it's made of, but here are some approximate weights:

* A standard paper postcard: about 0.1-0.2 ounces (2.8-5.7 grams)
* A cardboard postcard: about 0.3-0.5 ounces (8.6-14.2 grams)

To give you a better idea, here are some examples of common objects and their weights in ounces:

* A paper clip: 0.1 ounce (2.8 grams)
* A penny: 2.5 ounces (71 grams)
* A standard playing card: 0.2 ounce (5.7 grams)

So, a postcard is essentially weightless!


USPS postcard requirements


The United States Postal Service (USPS) has specific requirements for postcards. Here are the key guidelines:

1. **Size**: Postcards must be rectangular in shape and have a maximum size of 3.5 inches high x 5 inches wide.
2. **Weight**: Postcards must weigh no more than 1 ounce (28 grams).
3. **Thickness**: The thickness of a postcard is limited to 0.016 inch (0.406 mm) for standard postcards and 0.024 inch (0.610 mm) for extra-postcards.
4. **Addressing**: Postcards must have the recipient's address in the top left corner, with the return address (your name and address) on the right side of the card.
5. **Postage**: Postcards require a postage stamp equal to or greater than the first-class postcard rate, which is currently $0.36 per postcard (as of 2022). You can use a standard rectangular adhesive stamp or a digital stamp.
6. **Content**: While there are no specific content restrictions for postcards, you should avoid sending anything that might be considered offensive, threatening, or illegal.
7. **Perforation**: Postcards must have perforations on all four sides to allow for easy separation from other cards.

It's worth noting that USPS has specific requirements for postcard mailings in bulk. If you're planning to send a large quantity of postcards, you'll need to follow their guidelines for bulk mailing, which includes using a special permit and complying with certain formatting and labeling requirements.
