Choosing a truck cap is a significant investment, one that enhances your truck’s utility, security, and aesthetic appeal. However, the success of this investment hinges entirely on one critical factor: accurate sizing. Without a precise fit, even the most premium truck cap, like those from Leer, can lead to frustrating issues such as leaks, compromised security, diminished appearance, and even potential damage to your truck. This is where understanding and utilizing the Leer Truck Cap Size Chart becomes not just helpful, but absolutely essential.

The Leer Truck Cap Size Chart isn’t a single, universally published document with exact dimensions for every cap. Rather, it represents a comprehensive system of measurements, vehicle specifications, and model-specific designs that Leer employs to ensure their caps fit virtually every make and model of truck with factory-like precision. It’s the underlying principle guiding their custom-fit philosophy, ensuring that when you purchase a Leer cap, it’s designed specifically for your truck’s bed dimensions and contours, not a generic "one-size-fits-most" solution. This guide will delve into the intricacies of Leer’s sizing methodology, providing you with the knowledge and practical steps to ensure your next Leer truck cap fits perfectly.

Why Accurate Sizing Matters: The Foundation of Your Leer Cap Purchase

The importance of precise sizing for a Leer truck cap cannot be overstated. Unlike universal bed covers or tonneau covers, truck caps are rigid structures designed to integrate seamlessly with your truck’s bed rails and cab. Any discrepancy in dimensions can lead to a cascade of problems:

• Compromised Weather Sealing: A cap that’s too wide, too narrow, too long, or too short will not create a proper seal with the truck bed, leading to water leaks, dust intrusion, and damage to your cargo.
• Security Vulnerabilities: A poor fit can create gaps or allow the cap to be lifted or pried open more easily, defeating its purpose of securing your belongings.
• Aesthetic Discrepancies: A mis-sized cap looks out of place, detracting from your truck’s appearance and the overall value of your investment. Leer caps are known for their sleek, integrated look; an incorrect size ruins this.
• Installation Challenges: While Leer caps are designed for straightforward installation, an ill-fitting cap will be difficult to install correctly, potentially requiring modifications that void warranties or compromise structural integrity.
• Warranty Issues: Modifying a cap to fit an incorrect vehicle, or installing it improperly due to poor fitment, could potentially void your Leer warranty.



• Road Noise and Aerodynamics: Gaps due to improper sizing can increase wind noise and negatively impact your truck’s aerodynamics, potentially affecting fuel efficiency.

Understanding the Leer Truck Cap Size Chart principles and applying them correctly ensures that you avoid these pitfalls, securing a durable, functional, and aesthetically pleasing addition to your truck.

Understanding the Leer Sizing Philosophy: Beyond Just Bed Length

While many people assume truck cap sizing is simply about bed length (e.g., 5.5 ft, 6.5 ft, 8 ft), Leer’s approach is far more nuanced. The Leer Truck Cap Size Chart concept encompasses several critical dimensions and design considerations:

1. Bed Length: This is the most obvious measurement, from the bulkhead (front of the bed, near the cab) to the inside of the tailgate. Leer offers caps for standard short beds, long beds, and even some super short beds found on crew cab trucks.
2. Bed Width: The interior width of the truck bed, especially at the top of the bed rails. This ensures the cap sits flush without overhanging or being too narrow.
3. Bed Rail Profile: Modern truck beds are not always flat. Many have contoured bed caps, varying rail heights, or integrated cargo management systems. Leer caps are molded to match these specific profiles for a seamless fit and effective sealing.
4. Cab Height and Style: Leer offers different cap heights (e.g., cab-high, mid-rise, high-rise) to match the truck’s cab height or provide additional cargo volume. The cap’s front profile must also align with the truck’s cab for optimal aerodynamics and aesthetics.



5. Tailgate Design: The design of the cap’s rear door must complement the truck’s tailgate, allowing it to open and close freely without interference.
6. Year, Make, and Model Specificity: This is paramount. A 2020 Ford F-150 short bed will have different dimensions and contours than a 2020 Chevrolet Silverado short bed, or even a 2015 F-150 short bed. Leer designs caps specifically for each permutation.

Therefore, the Leer Truck Cap Size Chart is less about a single table of numbers and more about a precise matching process based on your vehicle’s exact specifications.

How to Use the Leer Truck Cap Size Chart: A Step-by-Step Guide to Measurement

Since there isn’t a single "chart" you can download with all Leer cap dimensions, the "how-to" involves accurately measuring your truck and then cross-referencing with Leer’s extensive fitment database, typically accessed through an authorized dealer. Here’s how to prepare:

1. Identify Your Truck’s Exact Specifications:

   • Year: Crucial, as bed designs change frequently.
   • Make: Ford, Chevrolet, Ram, Toyota, Nissan, etc.
   • Model: F-150, Silverado 1500, Ram 1500, Tacoma, Titan, etc.
   • Cab Style: Regular Cab, Extended Cab, Crew Cab (this often dictates bed length options).
   • Bed Length: This is paramount. Measure from the inside of the bulkhead (front of the bed, against the cab) to the inside of the tailgate, with the tailgate closed. Do not measure the top rail length, as some rails extend beyond the actual bed floor. Use a tape measure and round to the nearest half-inch or inch (e.g., 6.5 ft, 5.5 ft).

2. Measure Your Truck Bed (for verification):

   • Internal Bed Length: As described above.
   • Internal Bed Width: Measure the width of the bed at the top of the bed rails, ideally at the front (near the cab), middle, and rear (near the tailgate). Note any significant variations.
   • Bed Rail Height: Measure from the bed floor to the top of the bed rail. This helps confirm the overall depth.
   • Cab Height Match (Optional but Recommended): If you desire a cab-high cap, measure from the top of your bed rail to the highest point of your truck’s cab. This helps the dealer recommend the most aesthetically pleasing and functional cap height.

3. Consult an Authorized Leer Dealer: This is the most crucial step in utilizing the Leer Truck Cap Size Chart effectively.

   • Provide them with your exact truck year, make, model, cab style, and bed length.
   • A reputable dealer will use Leer’s proprietary fitment guide (their internal "size chart") to determine which Leer models are specifically designed for your truck. They can also show you options for different cap heights (cab-high, mid-rise, high-rise), window configurations, and accessories.
   • They may also want to take their own measurements to double-check and ensure precision, especially with newer or less common truck models.

Key Measurements for Your Leer Cap

While the dealer has the ultimate Leer Truck Cap Size Chart database, here are the core measurements you should have ready:

• Bed Length: The most critical dimension (e.g., 5′ 6", 6′ 6", 8′ 0").
• Bed Width: Measured across the top of the bed rails.
• Cab Height: For choosing between cab-high, mid-rise, or high-rise models.
• Truck Year, Make, Model: The absolute identifiers for Leer’s fitment database.

Navigating the Leer Product Line: Different Caps, Different Fits

Leer offers a diverse range of truck cap models, each with unique features and aesthetics. While the underlying sizing principles remain consistent, certain models are more popular for specific truck types or uses:

• 100R & 100XR: Popular cab-high models, often with various window and door options. Designed to follow the lines of your cab.
• 180 & 180XR: Mid-rise caps, offering more interior volume while maintaining a relatively sleek profile.
• 122: High-rise caps, maximizing cargo capacity, ideal for commercial or utility use.
• 700 Series & 750 Sport: Specific models with distinctive styling and features, designed to integrate uniquely with certain truck models.

Regardless of the model, Leer’s manufacturing process ensures that each cap, once the correct truck specifications are identified via the Leer Truck Cap Size Chart system, is built to precise tolerances for that specific vehicle.

Common Sizing Challenges and Solutions

• "My truck bed measures exactly 6 feet, but caps are 6.5 feet." Truck bed lengths are often nominal. A "6.5-foot bed" might actually measure 78-79 inches internally. Always measure precisely and communicate the actual measurement, but rely on the dealer’s knowledge of the standard nominal sizes.
• "Can I put a cap for a Ford on a Chevy?" Absolutely not. Leer caps are model-specific. The bed rail contours, width, and length vary too much between manufacturers and even between different years of the same model. There is no universal Leer Truck Cap Size Chart for cross-brand compatibility.
• "I have a unique bed liner or cargo system." Inform your dealer. Some aftermarket liners or factory cargo management systems (like RamBox or GM’s MultiPro tailgate) can affect cap fitment and may require specific cap configurations or adaptations.
• "What if my truck is an older model?" Leer maintains extensive fitment data for many older truck models. Provide the exact year, make, and model. If a new cap isn’t available, the dealer might be able to help locate a used one that fits.

Tips for a Perfect Fit and Installation

1. Measure Twice, Order Once: While your dealer will verify, having your own accurate measurements is a good starting point.
2. Clean Your Truck Bed Rails: Before installation, ensure your truck bed rails are clean and free of debris, old sealant, or residue to allow for a proper seal.
3. Professional Installation: While Leer caps can be self-installed, professional installation by an authorized Leer dealer is highly recommended. They have the experience, tools, and knowledge of the Leer Truck Cap Size Chart system to ensure a perfect, watertight, and secure fit, often backed by a warranty on their work. They also know how to properly wire the cap’s lights and brake light.
4. Regular Maintenance: Even with a perfect fit, periodically check the clamps and seals to ensure they remain secure and watertight.

Note on Pricing: The cost of a Leer truck cap is highly variable. It depends on the specific Leer model chosen (e.g., 100R vs. 700 Series), the features and options selected (e.g., carpeted headliner, remote keyless entry, roof racks, pet screens, interior lighting), and the authorized Leer dealer’s pricing structure, which can vary by region. For accurate pricing, always obtain a personalized quote from an authorized Leer dealer.

Frequently Asked Questions (FAQ) about Leer Truck Cap Sizing

Q1: Is there a universal Leer Truck Cap Size Chart I can download?
A1: No, not in the sense of a simple public chart with all dimensions. Leer’s sizing is based on specific truck year, make, and model fitment. Their "size chart" is an internal database used by authorized dealers to ensure precise matching for your vehicle.

Q2: Can I just measure my truck bed and order a cap online?
A2: While you can measure, it’s highly recommended to work with an authorized Leer dealer. They have access to Leer’s detailed fitment data, understand the nuances of different truck beds, and can ensure you order the correct model and options for a perfect fit. They also handle professional installation.

Q3: My truck bed is 6 feet long. Will a "6.5-foot bed" cap fit?
A3: Truck bed lengths are often given as nominal figures (e.g., 5.5 ft, 6.5 ft). Your 6-foot measurement might actually be the standard "short bed" or "standard bed" for your truck’s make and model, which is typically around 72-79 inches internally. Always provide your exact truck year, make, and model to the dealer, along with your measured bed length, to confirm the correct nominal size.

Q4: Do Leer caps fit trucks with bed liners or bed rail caps?
A4: Leer caps are designed to accommodate most factory bed liners and over-the-rail bed rail caps. However, if you have an aftermarket drop-in bed liner that is unusually thick or extends over the bed rails significantly, or a unique cargo management system like RamBox, it’s crucial to inform your Leer dealer, as it might affect the cap’s seal or require specific modifications.

Q5: Can I move my Leer cap from one truck to another if they’re both the same brand and bed length?
A5: It’s highly unlikely unless the trucks are the exact same year, make, and model. Even subtle design changes between model years (e.g., bed rail contours, cab height) can make a cap from one year incompatible with another, even if the nominal bed length is the same. Leer caps are custom-fit.

Q6: What if my truck is an older model not listed on Leer’s current website?
A6: Authorized Leer dealers have access to extensive historical fitment data. Provide them with your truck’s exact year, make, and model. They can determine if a new Leer cap is still manufactured for your specific vehicle.

Q7: How do I ensure a watertight seal with my Leer cap?
A7: A proper fit, achieved by using the correct Leer cap for your specific truck and professional installation by an authorized dealer, is the primary way to ensure a watertight seal. Dealers use specific seals and clamping techniques to prevent leaks. Regular checks of the seals and clamps are also recommended.
