The US Letter size, as the name suggests, is the standard in the United States. This size is perfect for businesses that operate primarily within the country’s borders. Its dimensions align perfectly with other typical document sizes used locally, ensuring a consistent and professional look.

Letterhead printing advice

A well-designed and correctly printed letterhead can create a great first impression, so it’s worth taking the time to get it right. Here are some essential tips for letterhead printing:

  • Print resolution: High resolution (300 dpi or more) is crucial. This ensures your prints aren’t blurry or pixelated, reflecting your professionalism.
  • Scaling: Design at actual size for the best results. Scaling your design during printing may distort your images and text.
  • Bleeds: Including bleeds in your design helps your background color or image extend to the edge of the page, eliminating unwanted white borders.
  • Proofreading: Always proofread before printing. Typos, incorrect information, or missing details can damage your brand’s credibility.
  • Color mode: Use CMYK color mode instead of RGB. This ensures accurate color reproduction in print.

Keep these pointers in mind when you embark on your letterhead printing journey. They’ll help ensure that the final product truly represents your brand and leaves a lasting impression.

As we wrap up this top guide, it’s important to remember that your letterhead is more than just a piece of paper. It’s a representation of your brand, your professionalism, and your attention to detail. Choosing the right size for your needs can make all the difference in how your message is perceived. 

So take the time to consider your options, use this guide as your trusty companion, and let’s usher with letterheads that truly capture the essence of your business. Here’s to creating impactful first impressions and memorable business communications!
