For owners of the venerable 1990 Ford F-150, equipping their trusty steed with a truck cap, also known as a camper shell, truck topper, or truck canopy, can transform it from a simple hauler into a versatile, secure, and weather-protected utility vehicle. Whether you’re a contractor needing to secure tools, an outdoor enthusiast looking for a dry place to store gear, or simply someone who wants to keep groceries safe from the elements, a truck cap is an invaluable accessory. However, the success of this transformation hinges entirely on one critical factor: getting the 1990 Ford F150 Truck Cap Size In Ft precisely right.

Unlike a universal accessory, truck caps are custom-fit to specific truck beds. A mismatch in size, even by an inch or two, can lead to poor sealing, leaks, aesthetic eyesores, and even structural integrity issues. This comprehensive guide will delve into every aspect of determining, understanding, and utilizing the correct truck cap size for your 1990 Ford F-150, ensuring you make an informed decision that perfectly complements your truck and lifestyle.

Understanding the 1990 Ford F-150 Bed Dimensions

The 1990 Ford F-150, part of the robust eighth generation of Ford’s F-Series trucks (produced from 1987 to 1991), primarily offered two main bed lengths. These dimensions are the cornerstone of selecting the correct truck cap.

1. Short Bed (Styleside): Approximately 6.5 Feet
   • Often referred to as 6′ 6" or 6.75 feet, the actual internal length of this bed is typically around 78 to 80 inches. When converted to feet, this is approximately 6.5 to 6.67 feet. This was the more common bed length for daily drivers and those who didn’t require maximum cargo capacity.
2. Long Bed (Styleside): Approximately 8 Feet
   • This bed option provided maximum cargo space, with an actual internal length usually around 96 to 98 inches. This translates directly to approximately 8 to 8.17 feet. It was favored by commercial users, contractors, or those frequently hauling large items.

In addition to length, the width of the F-150’s bed is also crucial. For the 1990 Styleside models, the internal bed width between the wheel wells is typically around 50 inches (approximately 4.17 feet), while the total internal width at the bed rails is generally around 63 to 65 inches (approximately 5.25 to 5.42 feet). Truck caps are designed to fit the external dimensions of the bed rails, ensuring a snug, weather-tight seal.

It’s important to note that while some 1990 F-150s were available with a "FlareSide" bed (with exterior fender flares), most truck caps are designed for the standard "Styleside" bed. While the length might be similar, the unique contours of a FlareSide bed often require specialized or custom-made caps, which are far less common in the used market. For the purpose of this guide, we primarily focus on the prevalent Styleside beds.

Why Accurate Sizing Matters: Benefits of a Properly Fitted Cap

The importance of precise sizing cannot be overstated. A perfectly fitted truck cap offers a multitude of benefits:

• Superior Protection from Elements: A cap that fits snugly seals out rain, snow, dust, and debris, keeping your cargo dry and clean. An ill-fitting cap will inevitably lead to leaks and water damage.



• Enhanced Security: Most truck caps come with lockable rear doors, transforming your open bed into a secure, enclosed trunk. This is invaluable for protecting tools, luggage, camping gear, or any valuable items from theft.
• Optimized Cargo Management: With a cap, you can stack items higher without worrying about them flying out. It allows for better organization and protects items from direct sunlight exposure, which can be damaging.
• Improved Fuel Efficiency (Minor): While not a primary reason for purchase, a well-designed, aerodynamically fitted truck cap can slightly reduce drag, potentially leading to a marginal improvement in fuel economy compared to an open bed.
• Increased Versatility: A cap opens up new possibilities for your truck. It can serve as a secure storage locker, a dry space for pets, or even a rudimentary sleeping area for camping, especially with taller cap designs.
• Aesthetic Appeal: A cap that perfectly matches the contours and lines of your 1990 F-150 looks like an integrated part of the vehicle, enhancing its overall appearance rather than looking like an afterthought.
• Preservation of Resale Value: A well-maintained, properly fitted cap can add to the resale value of your truck, or at least be sold separately if you decide to part ways with it.

How to Accurately Measure Your 1990 F-150 Bed for a Cap

Before you even think about looking for a cap, accurate measurement is paramount. Do not rely on old paperwork, online specs alone, or a friend’s truck. Measure your truck.

1. Clear the Truck Bed: Remove any bed liners, toolboxes, or debris that might interfere with accurate measurements.
2. Measure Length:
   • Use a sturdy tape measure (preferably a metal one for accuracy).
   • Measure from the inside edge of the front bulkhead (the wall closest to the cab) to the inside edge of the tailgate.
   • Measure along the top of the bed rails.
   • Take measurements at both the left and right sides of the bed, and in the middle, to account for any slight variations or past damage. Record the most consistent measurement.
   • Convert your inches measurement to feet (e.g., 78 inches / 12 = 6.5 feet).
3. Measure Width:
   • Measure the inside width of the bed rails at three points: near the cab, in the middle, and near the tailgate.
   • Again, measure along the top of the bed rails where the cap will rest.
   • Record these measurements. While the length is the primary determinant for cap fit, the width ensures a proper seal and aesthetics.
4. Measure Height (Optional but Recommended):
   • If you’re considering a "cab-high" cap (flush with the top of your truck’s cab), measure the height from the top of your bed rail to the highest point of your cab. This ensures the cap’s roofline will align properly. For mid-rise or high-rise caps, this measurement helps visualize the final look.

Pro Tip: Take your measurements multiple times to confirm consistency. A discrepancy of even half an inch can be the difference between a perfect fit and a frustrating experience.

Types of Truck Caps for the 1990 F-150 and Considerations

While the 1990 F-150 is an older model, a variety of cap types and materials were available and can still be found today, particularly in the used market.

• Materials:
  • Fiberglass: The most common type, offering a smooth, automotive-grade finish that can be color-matched to your truck. They are generally more aerodynamic, quieter, and aesthetically pleasing. They are durable but can crack under severe impact.
  • Aluminum: Lighter and typically more rugged and utilitarian. Often seen on work trucks, they are less expensive, highly durable, and come in various finishes (e.g., diamond plate). They might be noisier and less aesthetically refined than fiberglass.
• Styles:
  • Cab-High: Designed to be flush with the roofline of your 1990 F-150’s cab. This offers the most seamless, integrated look and maintains rear visibility.
  • Mid-Rise: Slightly taller than the cab, providing extra cargo volume without being overly bulky. A good compromise between aesthetics and utility.
  • High-Rise (Wedge/Walk-in): Significantly taller than the cab, offering maximum interior volume, often allowing a person to stand or walk inside. Ideal for campers or contractors needing abundant vertical space.
  • Commercial/Work Caps: Often made of aluminum, these are designed for heavy-duty use with reinforced construction, side access doors, toolboxes, and ladder racks.
• Features to Consider:
  • Windows: Sliding windows (for ventilation), fixed windows, or pop-out windows. Tinted windows for privacy.
  • Interior Lighting: Battery-powered or wired to the truck’s electrical system.
  • Roof Racks: For carrying ladders, kayaks, bicycles, or other oversized gear.
  • Carpeted Headliner: Reduces condensation, provides insulation, and a finished look.
  • Rear Door Options: Solid lift-up door, double doors, or a tailgate-style door.
  • Security: High-quality locks and reinforced latches.

Navigating the Market: Buying New vs. Used Caps

Given the age of the 1990 F-150, finding a brand new cap specifically designed for it might be challenging and expensive. Most manufacturers have moved on to newer truck generations. However, some custom manufacturers might still produce them, and the used market is a goldmine.

• Buying New (If Available):
  • Pros: Perfect fit, warranty, custom features, color matching, latest technology (e.g., LED lighting).
  • Cons: High cost, limited availability for older models.
• Buying Used:
  • Pros: Significantly more affordable, immediate availability, large selection (online marketplaces, salvage yards, specialty shops).
  • Cons: Finding an exact fit can be challenging, condition varies widely, no warranty, potential for hidden damage or leaks, color matching might be difficult.

Tips for Buying a Used Cap:

• Bring Your Measurements: Absolutely essential. Do not guess.
• Inspect Thoroughly: Check for cracks (especially fiberglass), dents (aluminum), rust on hinges/latches, condition of seals and weatherstripping, functionality of windows and locks.
• Check for Previous Leaks: Look for water stains or mold inside.
• Verify Fit: If possible, test fit it on your truck before purchasing. If not, ensure the seller provides precise measurements.
• Consider the Brand: Leer, ARE, Snugtop, Century, Jason, and Raider are reputable brands known for quality.

Installation, Maintenance, and Common Challenges

Installation:
You can either install a truck cap yourself or have it professionally installed.

• DIY: Requires a helper (caps are heavy and awkward), basic tools, and an understanding of clamping systems (J-clamps are common) and potential wiring for interior lights or third brake lights. Ensure the bed rails are clean and a good seal is established with weatherstripping.
• Professional: Recommended for peace of mind, especially for wiring, and to ensure a perfect, leak-free seal.

Maintenance:

• Regular Cleaning: Wash the cap with your truck to prevent dirt and grime buildup.
• Seal Inspection: Periodically check the weatherstripping around the bed rails and windows for cracks, tears, or compression. Replace as needed to prevent leaks.
• Hinge and Latch Lubrication: Keep moving parts lubricated to ensure smooth operation and prevent corrosion.
• Clamp Check: Re-tighten mounting clamps occasionally, as vibrations can loosen them over time.

Common Challenges and Solutions:

• Finding the Right Fit: For a 1990 F-150, this is the biggest hurdle. Patience and diligent searching on used markets are key. Be prepared to travel.
• Leaks: Often caused by worn seals, improper installation, or cracks. Solution: Replace seals, re-install with proper weatherstripping, or repair cracks with fiberglass repair kits.
• Electrical Issues: Dome lights or third brake lights not working. Solution: Check wiring connections, fuses, and bulb. Corrosion is common on older vehicles.
• Damaged Caps: Minor cracks or dents can often be repaired (fiberglass kits, body filler). Major structural damage might make a cap not worth buying.
• Rust on Bed Rails: Rust or unevenness on the truck’s bed rails can prevent a good seal. Solution: Clean, sand, and paint rusty areas. Use thicker weatherstripping or a foam gasket to compensate for minor irregularities.

Practical Advice and Actionable Insights

• Measure Thrice, Buy Once: This adage applies perfectly to truck caps. Precision prevents costly mistakes.
• Know Your Needs: Before looking, define how you’ll use the cap. This guides your choice of material, style, and features.
• Don’t Rush a Used Purchase: Take your time to inspect any used cap thoroughly. A cheap cap with hidden damage can end up costing more than a slightly more expensive one in good condition.
• Invest in Good Weatherstripping: Even with a perfect fit, quality weatherstripping is vital for a watertight seal. Don’t skimp on this inexpensive component.
• Consider Professional Installation for Wiring: While mounting the cap is straightforward, wiring lights can be tricky. If unsure, have a pro handle it.
• Regular Maintenance Extends Life: A few minutes of cleaning and inspection annually can significantly prolong the life of your truck cap and prevent issues.

Frequently Asked Questions (FAQ)

Q: Will a truck cap from a newer F-150 fit my 1990 model?
A: Highly unlikely. Ford significantly changed the bed dimensions and cab contours in later generations. A cap designed for a 1997-2003 F-150, for example, will not fit a 1990 model properly. Always check the specific generation and model year.

Q: Can I use a cap from another truck brand (e.g., Chevy, Dodge) on my 1990 F-150?
A: Almost certainly not. Truck beds vary in length, width, rail height, and cab contour across different manufacturers and even within different models from the same manufacturer. A proper fit is critical for sealing and aesthetics.

Q: How do I prevent leaks in my truck cap?
A: Ensure the bed rails are clean and free of debris before installation. Use high-quality weatherstripping (foam tape or bulb seal) along the entire perimeter where the cap meets the bed rails. Regularly inspect and replace worn-out seals around windows and the rear door.

Q: What’s the difference between a "camper shell" and a "truck cap"?
A: These terms are generally interchangeable and refer to the same accessory: a rigid cover that encloses the truck bed. "Camper shell" might imply a design more suited for sleeping, but both terms describe the same product.

Q: Does a truck cap affect gas mileage?
A: The impact is generally minimal. Some studies suggest a slight improvement in aerodynamics due to reduced drag from an open bed, potentially leading to a marginal increase in fuel efficiency. Others report no significant change or even a slight decrease due to added weight. The effect is usually negligible compared to driving habits.

Q: Are there specific caps for FlareSide beds on the 1990 F-150?
A: Yes, FlareSide beds have distinct fender flares that necessitate a cap designed specifically for their unique contours. These are much rarer than Styleside caps and can be very difficult to find on the used market.

Concluding Summary

For owners of the classic 1990 Ford F-150, adding a truck cap is an excellent way to enhance the utility, security, and versatility of their vehicle. The key to a successful addition, however, lies unequivocally in understanding and accurately measuring the truck’s bed dimensions. Whether your F-150 boasts the common 6.5-foot short bed or the more spacious 8-foot long bed, precise measurements are your best friend in finding a cap that fits perfectly.

While finding a new cap for an older truck might be a challenge, the robust used market often holds treasures. By knowing your truck’s exact "1990 Ford F150 Truck Cap Size In Ft" and diligently inspecting potential purchases, you can secure a cap that provides years of reliable service. Remember, a properly fitted and maintained truck cap isn’t just an accessory; it’s an extension of your truck’s capabilities, protecting your cargo and enhancing your adventures for years to come.
