21″ Large Letters

21″ Large Letters

Want your message to really jump out at passing traffic? Our 21″ large letters are designed for maximum visibility when you need to make a bold statement.

We normally use 10.5″ letters, which allow for up to 4 lines of text and more characters per line. The 21″ letters are a special upgrade option with different layout limits and a more limited character set, but dramatically larger text.

How the 21″ letters work

  • Letter height: 21″ tall (about double our regular 10.5″)
  • Characters per line: About 8 characters per line
  • Rows used: Each line of 21″ letters uses 2 rows on the sign
  • Maximum lines: Because of this, a 21″ message can be up to 3 lines instead of 4

So, compared to our regular setup:

  • Regular letters: Up to 4 lines, more characters per line
  • 21″ letters: much larger text

Limited letter availability

Our 21″ letter set is limited in quantity, so:

  • Not every letter or symbol may be available at all times
  • Messages may need to be shortened or adjusted to fit available characters
  • Simple, bold wording works best (short words, no long phrases)

If you’re not sure whether your message will fit, we can help you reword it to work with the large letters.

Best uses for 21″ letters

The 21″ upgrade is ideal when:

  • You want maximum impact from farther away
  • You’re promoting a short, powerful message
  • You’re highlighting a name, date, or big event

Examples that work well with 21″ letters:

  • “GRAND OPEN”
  • “NOW HIRING”
  • “BIG SALE”
  • “OPEN HOUSE”

Short, punchy phrases are where these letters shine.

Things to consider before choosing 21″ letters

Because of the size and limits:

  • Your message must be shorter than a standard 10.5″ letter message
  • You are limited to about 8 characters per line
  • 2 rows will be needed to fit the larger letters

If you need longer messages, detailed info, or multiple lines of text, our regular 10.5″ letters are usually the better choice.

Not sure which size is right for you?

Tell us:

  • What you want your sign to say
  • Where the sign will be viewed from (road speed, distance, etc.)

We’ll recommend whether 10.5″ regular letters or 21″ large letters will give you the best visibility and readability for your message.
