When I first started hunting for a Motor Trend car cover, the size puzzle felt like trying to fit a square peg into a round hole. There’s plenty of advice floating around: “Just get the next size up,” or “Measure roughly and you’ll be fine.” But that approach almost got me into trouble, overly loose covers flapping in the wind can do more harm than good, while tight covers stretch seams and risk tearing. I learned that the key constraint is precise vehicle length, not guesswork or width guesses.
Why Length Is the Real Deal for Motor Trend Cover Sizes
Motor Trend sizes their covers primarily by your car’s length from bumper to bumper, not width or height. The reasoning is simple: length affects overall coverage most directly, and the covers come with stretch panels or elastic hems that adjust for width variations. Ignoring this can lead to buying a cover that either won’t fully protect your bumpers or hangs too loosely, becoming a sail in any breeze.
Here’s why this matters: I once saw a vintage coupe owner pick a cover “a bit too large to be safe.” The result? The loose fabric whipped against the paint during windy days, causing micro-scratches along the doors. That’s a classic failure mode caused by ignoring strict length fitting.
How to Measure Your Car With Purpose, Not Just “Close Enough”
Grab a tape measure and take your time measuring from the very front edge of your bumper to the very rear edge. Don’t include add-ons like removable bike racks or temporary spoilers. Permanent accessories like fixed roof racks count though, they add to length.
If you’re on the fence between two sizes, here’s where understanding cover material helps. Motor Trend covers often have flexible hems that allow a few inches’ play. If your car length is just shy of a size boundary, pick the smaller size for snug protection; if your vehicle has protrusions like side mirrors or permanent spoilers adding length, lean toward the larger size.
Motor Trend Size Chart That Cuts Through Confusion
| Size | Vehicle Length (inches) | Typical Vehicles |
|---|---|---|
| Small | Up to 168" | Compact hatchbacks, subcompacts |
| Medium | 168"–180" | Midsize sedans, small SUVs |
| Large | 180"–192" | Full-size sedans, midsize trucks |
| X-Large | 192"–204" | Large SUVs, minivans |
| XX-Large | 204"–216" | Extended trucks, full vans |
This chart is grounded in Motor Trend’s approach, length-based with enough margin for elastic adjustments, and it reflects a practical balance between coverage and fit.
Composite Example: Why Choosing X-Large for a 16-Foot Camry Worked
A friend of mine owns a 2018 Toyota Camry measuring about 192 inches (exactly 16 feet). According to the chart, Large fits up to 192 inches but skirts the top end; X-Large covers 192–204 inches. Because his car has wider side mirrors and he parks outdoors where wind gusts are common, he chose X-Large. The result was just enough extra room so the cover didn’t stress seams yet stayed tight enough to avoid wind flapping.
If he had blindly grabbed Large, there was a real risk of tight spots around mirrors or tugging on zippers, things that degrade cover life quickly.
Common Mistakes That Undermine Your Cover’s Protection
- Skipping measurement altogether: This is a trap that leads to returns and frustration.
- Including detachable accessories in measurements: Only permanent fixtures count.
- Overestimating “roominess” benefits: Loose covers catch wind and cause abrasion.
- Focusing on width instead of length: Width is less variable; covers handle it with elastic features.
- Ignoring cover material stretch: Some models tolerate borderline sizing but don’t bank on it if you want reliability.
When Your Vehicle’s Shape Breaks the Rules
If you have something unconventional, a pickup with an extended bed cap, or an aggressive spoiler, don’t rely solely on length charts. Measure with those accessories installed and consider one size up if you want full coverage without strain.
However, know this trade-off: one size larger can make fit looser and more prone to wind damage if your accessories don’t actually add much length but bulk elsewhere.
Final Thought: Measuring Is Your Best Protection Strategy
Knowing your precise length removes guesswork and safeguards you from weak fits that damage paint from flapping or stress seams from pulling tight. The best part? Once I committed to this simple measurement method before ordering any Motor Trend cover, my hassle factor dropped dramatically, I stopped returning covers or wrestling with ill fits altogether.
What You Should Do Next
Before clicking “buy”:
- Find your vehicle’s exact bumper-to-bumper length using a tape measure.
- Check against Motor Trend’s length-based size chart above.
- Factor in permanent accessories by adding their length if needed.
- Choose the size at or just above your measured length without overshooting by more than 3–4 inches.
- Remember some stretch in material helps but don’t rely on it as an excuse for loose fit.
This disciplined approach will save time, money, and frustration while keeping your vehicle truly protected year-round.
Your car deserves more than guesswork, it deserves a cover that fits like it was made just for it. Take that tape measure out now; it’s easier than it looks and will reward you every time you pull on your Motor Trend cover.
