What are the dimensions of a postcard in inches


The standard dimensions for a postcard can vary depending on the country and postal service, but here are some common sizes:

**United States:**

* Standard size: 3.5 x 5.5 inches (8.9 cm x 14 cm)
* Jumbo size: 4.25 x 6 inches (10.8 cm x 15.2 cm)

**International:**

* ISO standard size: 4 x 6 inches (10.2 cm x 15.2 cm)
* European standard size: 3.9 x 5.7 inches (9.9 cm x 14.5 cm)

Keep in mind that these are general guidelines, and some countries or postal services may have slightly different dimensions for postcards.

It's also worth noting that when designing a postcard, you should leave enough space around the edges to accommodate any perforations or folding. Typically, this means leaving about 0.25-0.5 inches (6-13 mm) of white space around the edges.


What are the dimensions of a postcard in pixels


The dimensions of a standard postcard can vary depending on the country and type of card, but here are some common sizes:

* In the United States:
+ Standard postcard: 3.5 inches wide x 5.8 inches long (89 mm x 147 mm)
+ Large postcard: 4.25 inches wide x 6.75 inches long (108 mm x 171 mm)
* In Canada:
+ Standard postcard: 4 inches wide x 6 inches long (102 mm x 152 mm)
* In the United Kingdom:
+ Standard postcard: 3.5 inches wide x 5 inches long (89 mm x 127 mm)

To convert these dimensions to pixels, we need to know the resolution of the image file. A common resolution for digital images is 72 pixels per inch (PPI). Here are the conversions:

* US Standard Postcard:
+ Width: 252 pixels (3.5 inches x 72 PPI)
+ Height: 416 pixels (5.8 inches x 72 PPI)
* US Large Postcard:
+ Width: 306 pixels (4.25 inches x 72 PPI)
+ Height: 486 pixels (6.75 inches x 72 PPI)
* Canadian Standard Postcard:
+ Width: 288 pixels (4 inches x 72 PPI)
+ Height: 432 pixels (6 inches x 72 PPI)
* UK Standard Postcard:
+ Width: 252 pixels (3.5 inches x 72 PPI)
+ Height: 360 pixels (5 inches x 72 PPI)

Keep in mind that these are approximate conversions, as the actual dimensions may vary slightly depending on the design and layout of your postcard.


Postcard size in inches


The standard postcard sizes in inches are:

* Standard: 3.5 x 5.5 inches (8.9 cm x 14 cm)
* Large: 4.25 x 6.75 inches (10.8 cm x 17.1 cm)
* Jumbo: 5.0 x 7.0 inches (12.7 cm x 17.8 cm)

Keep in mind that these sizes are not strictly standard, and some postcards may vary slightly depending on the manufacturer or designer. However, the 3.5 x 5.5 inch size is by far the most common and widely accepted postcard size.


Postcard size in mm


Here are some common postcard sizes in millimeters:

* Standard postcard: 89 x 148 mm (3.5 x 5.8 inches)
* Large postcard: 100 x 150 mm (3.9 x 5.9 inches)
* Square postcard: 98 x 98 mm (3.9 x 3.9 inches)
* Mini postcard: 62 x 89 mm (2.4 x 3.5 inches)
* Maxi postcard: 110 x 160 mm (4.3 x 6.3 inches)

Note that these sizes are not universally standard and may vary depending on the country or region you're in.


4x6 postcard size in cm


A standard 4x6 inch postcard would be equivalent to:

* Length: approximately 10.2 cm (4 inches)
* Width: approximately 15.3 cm (6 inches)

So, a 4x6 inch postcard would have dimensions of around 10.2 x 15.3 cm in centimeters.


Postcard size photo


Postcard-sized photos are a great option too!

For postcard-sized photos (typically around 3.5 x 5 inches or 8.9 x 12.7 cm), here are some guidelines to keep in mind:

1. **Resolution**: For postcard-sized prints, a minimum resolution of 300 pixels per inch (PPI) is recommended. This will ensure that the image remains clear and sharp when printed.
2. **Image size**: A good rule of thumb is to use an image that's around 1000-1200 pixels in width. This will give you some flexibility when cropping or resizing the image for printing.
3. **Aspect ratio**: Since postcards are typically rectangular, aim for a 2:3 or 3:5 aspect ratio (width:height) to ensure your image fits well on the card.
4. **Composition**: Consider using a central composition, as this works well with the rectangular shape of postcards. You can also use negative space effectively by leaving some breathing room around your subject.
5. **Color and contrast**: Postcard printing often favors vibrant colors, so consider using bright and saturated hues to make your image pop. However, be mindful of contrast levels, as high-contrast images might not print well.

When it comes to editing postcard-sized photos, keep the following in mind:

1. **Crop wisely**: Since you're working with a smaller canvas, crop your image carefully to focus attention on your subject.
2. **Adjust brightness and contrast**: Make adjustments to balance out the colors and ensure they print well.
3. **Use sharpening tools**: Apply gentle sharpening to enhance details without introducing noise or artifacts.

Remember that postcard-sized photos are meant to be shared and enjoyed, so don't be afraid to get creative and have fun with your editing!


USPS postcard size


USPS postcard size is a standard size for postcards that can be mailed at the postcard rate. The dimensions of a USPS postcard are:

* Length: 3.5 inches (89 mm)
* Width: 5.0 inches (127 mm)

This size is slightly smaller than the international postcard size, which is typically 4-6 inches long and 5-7 inches wide.

USPS has specific guidelines for postcards, including:

1. The postcard must be no larger than 3.5 x 5.0 inches.
2. The postcard must have a blank space of at least 0.25 inch (6 mm) from the top edge to the address area.
3. The postcard can have a design or artwork on one side, but it must not obstruct the address area.

Postcards that meet these guidelines can be mailed at the standard postcard rate, which is currently $0.36 in the United States as of 2022.
