Dimensional Letters Cost: Pricing by Size & Material

Dimensional letters are the most popular entry point into custom signage — and for good reason. They deliver a professional 3D look, work in virtually any space, and start at a lower price point than full panel signs. But pricing varies significantly based on material, letter height, thickness, and mounting method.

This guide breaks down exactly what dimensional letters cost in 2026, so you can budget accurately for your project.

Dimensional Letters Starting Prices

A standard set of dimensional letters (typically 4-8 characters for a company name) starts from $1,200. That includes design, CNC fabrication, finish, standoff hardware, and a mounting template.

Per-letter pricing depends heavily on material and size:

  • PVC foam (Sintra): $80 - $150 per letter at 6-8 inches (15-20 cm) tall
  • Acrylic: $100 - $200 per letter at 6-8 inches (15-20 cm) tall
  • Stained plywood or MDF: $100 - $180 per letter at 6-8 inches (15-20 cm) tall
  • Solid hardwood (walnut, oak): $150 - $300 per letter at 6-8 inches (15-20 cm) tall
  • Brushed or painted metal: $200 - $400+ per letter at 6-8 inches (15-20 cm) tall

How Size Affects Dimensional Letter Pricing

Letter height is the primary size driver. As letters get taller, material usage, machine time, and structural requirements all increase.

Small: 4-6 Inches (10-15 cm)

Best for suite signs, door numbers, and secondary text. At this scale, even premium materials remain affordable. A set of 4-6 inch acrylic letters typically costs $800-$1,500 total.

Medium: 8-12 Inches (20-30 cm)

The most common size for lobby and reception signs. Readable from 10-15 feet (3-4.5 meters) away and proportional to most standard walls. Budget $1,200-$3,000 for a typical company name.

Large: 14-24 Inches (36-61 cm)

For high-ceiling lobbies, exterior applications, and statement walls. At this scale, material thickness and mounting become critical. Letters this size need 0.75 to 1.5 inch (2-4 cm) thickness to look proportional. Budget $2,500-$6,000+ depending on material and letter count.

Extra Large: 24+ Inches (61+ cm)

These are architectural-scale letters for atriums, storefronts, and building facades. Structural engineering becomes a factor — letters may need internal framing or multiple mounting points. Pricing starts from $400-$800+ per letter.

Material Comparison for Dimensional Letters

Acrylic

The go-to for modern, clean aesthetics. Available clear, frosted, colored, or painted. CNC-cut edges can be polished to a glass-like finish or left matte. Thickness options from 0.25 inch (6 mm) to 1 inch (25 mm). Extremely durable indoors — will not yellow, warp, or degrade for decades.

Best for: tech companies, medical offices, modern brands, any space where you want a sleek look.

Wood

Natural warmth that photographs and vinyl cannot replicate. Options range from budget-friendly Baltic birch plywood (stained or painted) to premium solid walnut or white oak. CNC cutting produces clean edges that can be left natural, stained, or painted.

Best for: law firms, restaurants, boutique retail, creative agencies, hospitality.

PVC Foam (Sintra/Expanded PVC)

The most affordable option for dimensional letters. Lightweight, paintable, and surprisingly durable indoors. Available in thicknesses from 0.25 to 1 inch (6-25 mm). The surface can be painted any color and accepts vinyl lettering.

Best for: budget-conscious projects, temporary installations, lightweight applications where wall strength is limited.

HDU Foam (High-Density Urethane)

Denser than PVC foam, HDU carves beautifully and holds fine detail. It is paintable, sandable, and weather-resistant — making it one of the few foam options suitable for exterior use. Pricing sits between PVC and solid wood.

Metal

Brushed aluminum, painted steel, or brass create a premium look that commands attention. Metal letters are heavier and require more robust mounting hardware. They are the most expensive option but deliver unmatched durability and presence.

Best for: high-end offices, financial services, brands wanting maximum gravitas.

Mounting Methods and Their Cost Impact

Standoff Pins

The most popular mounting method. Letters sit 0.5 to 1 inch (1-2.5 cm) off the wall on metal or acrylic posts. This creates a shadow effect that adds depth and visibility. Standoffs add $5-$15 per mounting point to the total cost.

Stud Mount (Flush)

Hidden threaded studs are embedded in the back of each letter, then inserted into pre-drilled holes in the wall. The letter appears to float directly on the surface with no visible hardware. This method costs roughly the same as standoffs but requires more precise installation.

French Cleat

For heavier letters or situations where individual stud mounting is impractical. A metal rail on the wall engages a matching rail on the letter back. Adds $50-$150 to mounting hardware costs but makes installation and future removal much easier.

Additional Cost Factors

  • Paint or finish: Standard solid colors are included. Custom color matching (Pantone, brand colors) adds $100-$300 per set.
  • Logo integration: If your logo is part of the letter set, complex shapes with thin details or internal cutouts add machine time and cost 20-40% more than straight text.
  • Backlighting: Adding LED halo lighting behind dimensional letters adds $800-$2,000+ depending on letter count and size. This turns a $1,200 letter set into a $2,500+ project.
  • Rush production: Standard lead time is 2-3 weeks. Rush orders (under 7 days) typically add 25-50% to the base price.

Getting an Accurate Quote

For a precise dimensional letter quote, provide: the text or logo, desired height, material preference, and a photo of the wall where they will be mounted. This gives the fabricator enough information to quote accurately without back-and-forth.

Frequently Asked Questions

Dimensional letters start from $1,200 for a standard set (typically 4-8 letters at 6-12 inches tall). Per-letter pricing runs $80-$400+ depending on material, height, and thickness.

PVC foam (Sintra) and HDU foam are the most affordable options. Acrylic and stained plywood offer a mid-range option, while brushed metal and solid hardwood are premium.

Most dimensional letters use standoff pins or studs that hold the letter 0.5 to 1 inch off the wall, creating a shadow effect. Flush-mount options use construction adhesive or hidden French cleats for a cleaner look.
