How Much Do 24-Inch Channel Letters Cost? Sign Sizing & Pricing

How much do 24-inch channel letters cost? It is one of the most common size requests we get — and one of the easiest to misquote. The price depends on how many letters, how they are lit, and how they mount, not just the number 24.

This is how we price a 24-inch channel letter set, how letter height is measured in the first place, and what changes the number up and down.

1. First, how "24 inches" is measured

Letter height is measured as cap height — the height of a capital letter like "H" or "M", not including accents, descenders, or the extra space a mounting template needs. If you are replacing an existing sign, measure the capital letters, not the full panel.

24 inches is about 61 cm. That is a common storefront size: readable from a moving car, but not oversized. It is the size we quote most often for strip-mall tenants, restaurants, and small retail fronts.

2. How much do 24-inch channel letters cost?

Our channel letters start at $800 factory-direct, and a 24-inch set is a mid-size build. The final number is driven by four things:

• Number of letters — a 4-letter set costs less than a 12-letter set; each letter is its own box with its own LEDs.
• Front-lit vs halo-lit — front-lit is the most economical; halo-lit adds standoffs and cost.
• Finish — painted aluminum returns cost less than brushed stainless or mirror finishes.
• Single colour vs RGB — RGB adds addressable LEDs and a controller.

3. Why price does not scale evenly with size

Going from 18-inch to 24-inch letters does not add a third to the price. You are paying for each letter's acrylic face, LED modules, returns, and mounting hardware — and some of those are near-fixed costs. Letter count and finish usually move the number more than the last few inches of height.

In practice, a 24-inch build is usually a small-to-medium job. The jump to 36-inch or 48-inch letters starts to push the price because the letter area — and therefore the acrylic and LED count — grows quickly.

4. Inch-to-centimetre conversion

A quick reference for the sizes people ask about most:

If you already have an existing sign, measure the capital letter height in inches and send us a photo. For the full conversion chart, see our sign size conversion guide. We can match the size exactly, so the new sign fits the same footprint. For US sign codes and sizing guidelines, the International Sign Association is a good reference.

5. What to send for an exact 24-inch quote

To turn "24 inches" into a fixed DDP price, send us your logo, the exact letter height, and how many letters are in the sign. We return a line-item quote with production and DDP shipping shown separately.

Frequently asked questions

How much do 24-inch channel letters cost?

Channel letters start at $800 factory-direct, and a 24-inch set is a mid-size build. The exact price depends on letter count, lighting type, finish, and whether you choose single-colour or RGB.

How is letter height measured?

Letter height is measured as cap height — the height of a capital letter like "H" or "M". It does not include accents, descenders, or the mounting template.

What is the difference between 24-inch and 36-inch letters?

36-inch letters are larger and more visible from a distance, but they cost more because each letter uses more acrylic and more LEDs. For most strip-mall storefronts, 24-inch is the sweet spot between visibility and cost.

Can you match an existing sign size?

Yes. Send a photo of the existing sign with a rough measurement, and we match the cap height so the new sign fits the same footprint. For US sign codes and sizing guidelines, the International Sign Association is a good reference.
