Low Profile vs. Full Height Bed Rack: How to Choose
If you're shopping for a bed rack, height is the first decision that shapes everything else. A low profile bed rack sits close to your bed rails and barely changes how your truck drives. A full height bed rack rides near or above your cab roofline and opens up serious cargo room ā at the cost of wind drag, weight up high, and garage clearance headaches. Most buyers don't realize there's a middle option too, and picking the wrong height is the #1 regret we hear about after the rack is already bolted on.
š Key Takeaways
- Low profile racks sit roughly 0-9 inches above the bed rail, full height racks run 19-30+ inches ā the gap is bigger than most buyers expect.
- Fuel economy drops as height goes up: about 0.5-1 mpg for low profile, up to 2-4 mpg for full height with a tent mounted.
- Garage doors average 7 feet tall. Stack your truck's height, rack height, and a closed rooftop tent together before you assume it'll fit.
- Mid-height racks (10-18 inches) are the option most comparison guides skip, and they fit the majority of overlanders best.
- Side panel and accessory mounting (awnings, MOLLE, recovery gear) gets dramatically easier as rack height increases.
ā Quick Answer
Go low profile if you want minimal impact on driving, fuel economy, and garage parking, and you're only mounting a tent or light cargo. Go full height if you need maximum room for awnings, recovery gear, and tall accessories, and you don't care about the extra wind drag or a higher center of gravity. If you're stuck between the two, mid-height usually wins ā it gives you most of the storage benefit of a full height rack without the worst of the drawbacks.
š What "Low," "Mid," and "Full Height" Actually Mean
Most buying guides describe height in vague terms like "below the cab" or "above the roofline." That's not useful when you're trying to measure your own garage door. Here's roughly what each category means in real inches above the bed rail, based on the most common rack lines on the market:
Low Profile
Roughly 0-9 inches above the bed rail. Sits at or just above the bed itself.
Mid Height
Roughly 10-18 inches above the bed rail. Clears most gear stored underneath.
Full Height
Roughly 19-30+ inches above the bed rail, landing at or above the cab roof.
Exact numbers shift by truck model and brand, so treat these as planning ranges, not a spec sheet. Measure your own truck before you buy.
ā¬ļø Low Profile Bed Racks: Pros and Cons
A low profile bed rack ā sometimes sold as "bed bars" ā is the simplest version of this product. Two crossbars, basic mounting brackets, done.
Pros
- Smallest hit to fuel economy of any rack style
- Lowest center of gravity ā feels closer to stock when driving and cornering
- Fits in standard garages without a second thought
- Cheapest option, usually $499-$700
- Often compatible with tonneau covers
Cons
- Almost no room to mount side panels, awnings, or recovery gear
- Limits what you can store under a rooftop tent
- No real protection or structure if you're hauling tall cargo
ā¬ļø Full Height Bed Racks: Pros and Cons
A full height rack is built for people who want to use every inch of vertical space the bed offers, and who plan to load it up with accessories on top of a tent.
Pros
- Maximum room for awnings, MOLLE panels, recovery boards, and jerry cans
- Best fit for large or heavy hardshell rooftop tents
- Can extend over the cab for hauling ladders, lumber, or kayaks
- Easiest gear organization for long overland trips
Cons
- Worst fuel economy hit ā up to 2-4 mpg with a tent mounted
- Raises center of gravity, noticeable in corners and on uneven trails
- Frequently too tall for a standard 7-foot garage door once a tent is added
- Most expensive category, often $1,100-$1,950
āļø Mid-Height: The Option Most Guides Skip
Almost every comparison online jumps straight from "low" to "full height" and treats mid-height as an afterthought. That's a mistake, because mid-height is genuinely where most overlanders end up happiest.
At 10-18 inches, you get real storage space underneath for coolers, recovery gear, or drawer systems, plus enough crossbar and side panel room for the accessories most people actually mount. The fuel economy hit stays moderate ā closer to 1-2 mpg ā and the center of gravity change is small enough that you won't notice it on the highway. If you're not sure which way to go, start your shopping here before you talk yourself into full height "just in case."
š Side-by-Side Comparison
| Factor | Low Profile | Mid Height | Full Height |
|---|---|---|---|
| Height above bed rail | 0-9 in | 10-18 in | 19-30+ in |
| Fuel economy impact | 0.5-1 mpg | 1-2 mpg | 2-4 mpg |
| Typical price range | $499-$700 | $633-$1,020 | $1,100-$1,950 |
| Garage friendliness | Excellent | Good, check tent height | Often won't fit with tent |
| Accessory mounting room | Minimal | Moderate | Maximum |
| Best for | Daily drivers, light campers | Most overlanders | Heavy gear haulers, long trips |
šŖ Garage Clearance and Rooftop Tent Fit
This is the step buyers skip, and it's the one that causes the most regret. A standard residential garage door is about 7 feet tall. To know if your setup will actually fit, add three numbers: your truck's stock height, your rack's height above the bed rail, and your closed rooftop tent's height. If that total clears 7 feet, you're either parking outside or trimming your options.
- Step 1: Find your truck's stock height from the manufacturer spec sheet.
- Step 2: Add your rack's height above the bed rail (use the ranges above if you don't have exact numbers yet).
- Step 3: Add your closed rooftop tent's height, if you're mounting one.
- Step 4: Compare the total to your garage door height. Measure the door ā don't assume 7 feet.
Height also changes how easy it is to climb into a rooftop tent. Low and mid-height racks keep the tent's entry ladder shorter and the climb less awkward ā a detail that comes up constantly in owner forums, usually from someone who didn't think about it until their first trip.

ā Frequently Asked Questions
Is a low profile bed rack strong enough for a rooftop tent?
Yes. Most low profile racks are rated for 300+ lbs of dynamic load, which covers the vast majority of soft-shell and many hardshell tents. Check the specific rack's dynamic rating against your tent's weight before buying.
How much height does a full height bed rack actually add?
Roughly 19-30+ inches above the bed rail depending on the brand and your truck's cab height. Add a closed rooftop tent on top and you can easily add another 8-12 inches.
Can I upgrade from low profile to full height later?
Sometimes, but not always. Some brands sell height-adjustable leg kits, but many low profile and full height racks use entirely different leg and mounting designs. If you think you'll want more height later, it's worth checking a modular system like Leitner ACS or OVS Freedom Rack upfront.
Does a low profile bed rack work with a tonneau cover?
Often yes, especially with retractable covers that have T-slot rails. Full height and mid-height racks are less consistently compatible since their legs sit further into the bed. Check our tonneau cover collection for compatible pairings.
Which height is best for a Toyota Tacoma?
Mid-height is the most common choice for Tacoma overland builds, since it balances storage with a manageable total height for garages and trail clearance. Low profile is popular for daily-driven Tacomas with a simple tent setup.
Will a full height rack hurt my gas mileage that much?
It depends on what's mounted. An empty full height rack has a modest impact, but adding a rooftop tent or cargo box on top creates real wind resistance ā owners commonly report 2-4 mpg lower on the highway compared to no rack at all.
Should I buy steel or aluminum for a low profile setup?
Either works for low profile use, but the material question matters more as height and load increase. We break down the durability and weight tradeoffs in our steel vs. aluminum bed rack guide.
š Final Verdict
There's no universally "right" height ā only the right height for how you actually use your truck. If you drive it daily and park in a garage, low profile keeps that simple. If you're building a dedicated overland rig and garage space isn't a factor, full height earns its keep. And if you're not fully sure yet, mid-height is the safest starting point, because it's the easiest to live with while you figure out what gear you'll actually carry long-term.
- Measure your garage door and stock truck height before you shop, not after.
- Match dynamic load rating to your tent and gear weight, not just static capacity.
- If you're unsure, start at mid-height ā it's the easiest to live with.
