You’ve seen them. Those massive, towering figures that make a standard two-story suburban home look like a dollhouse. Putting a 20 foot tall inflatable santa in your front yard isn't just a decorating choice; it's a structural engineering project. Most people buy these things on a whim after seeing a viral TikTok or a neighbor's display, only to realize that a twenty-foot nylon giant has the same aerodynamic properties as a sailboat wing. If you don't know what you're doing, that Santa isn't staying in your yard. It’s going to end up three blocks away, tangled in a power line, or worse, face-down in a puddle looking like a holiday tragedy.
Size matters. But physics matters more.
The wind is your absolute worst enemy
When you move from a standard seven-foot inflatable to a 20 foot tall inflatable santa, the surface area doesn't just double. It quadruples. You are dealing with a massive amount of drag. Brands like Occasions or Gemmy—the big names in the inflatable world—usually include stakes and tethers, but honestly, the stock equipment is often laughable for something this size. You’re basically trying to hold down a hot air balloon with plastic tent pegs. It won't work.
If the wind hits 15 or 20 miles per hour, a giant Santa becomes a liability. I’ve seen tethers snap like guitar strings because the owner relied on the thin nylon cord that came in the box. Professional decorators usually swap those out for paracord or high-tensile braided polyester. You want something with at least a 200-pound break strength. Also, skip the plastic stakes. Go to a hardware store and buy 12-inch galvanized steel landscape staples or rebar stakes. Hammer them in at a 45-degree angle away from the inflatable. It’s the only way to sleep soundly when the December gusts start kicking up.

Powering the beast
Most people assume they can just plug their 20 foot tall inflatable santa into the same outdoor outlet as their C9 LED strings. Big mistake. These massive units require high-output blowers, sometimes two of them, to maintain enough internal pressure to keep the head from sagging. A typical 20-foot model might pull 2 to 3 amps just for the fan. If you have a whole "National Lampoon" setup going on, you’re going to trip a breaker faster than you can say "St. Nick."
Check your GFCI outlets. These are the ones with the "test" and "reset" buttons. Outdoor inflatables are notorious for sucking in moisture, which can cause a ground fault. If your Santa keeps deflating, it might not be a hole in the fabric; it might just be your outlet doing its job and cutting power to prevent a fire. Keep the blower off the muddy ground. Pro tip: place the blower on a couple of flat bricks or a wooden pallet. This keeps it from sucking in wet leaves or snow, which will burn out the motor in a single season.
The "Sad Santa" syndrome and how to fix it
Nothing ruins the holiday vibe like a limp, half-deflated Santa leaning drunkenly against your gutter. This usually happens for two reasons: low internal pressure or poor tethering. If the fabric gets soaked with freezing rain, it becomes incredibly heavy. A 20 foot tall inflatable santa can hold gallons of water in the folds of its hat or arms. That weight makes it impossible for the fan to push enough air to keep it upright.

You’ve gotta be proactive. If the forecast calls for heavy snow or ice, turn it off and let it deflate. It’s better to have a flat Santa covered in snow than a standing one that collapses and rips under the weight of an ice storm. If he’s already up and leaning, check your top tethers. Most people only tie down the base. For a 20-footer, you absolutely must use the "mid-point" or "shoulder" tie-downs. These should reach out wide to the sides, creating a tripod effect that stabilizes the upper half of the body.
Storage is where the real work begins
The holiday is over. You’re tired. You just want to shove the nylon into a plastic bin and forget about it until next November. Don't do that. If you pack away a 20 foot tall inflatable santa while it’s even slightly damp, you’ll open that bin next year to find a moldy, black-spotted mess that smells like a wet basement. The smell of mildew is almost impossible to get out of specialized outdoor nylon.
Dry it out completely. I mean bone-dry. Inflate it on a clear, sunny day in January and let the sun do the work. Once it’s dry, fold it loosely. Avoid tight creases, which can weaken the internal coating that makes the fabric airtight.

Essential Checklist for Giant Inflatable Success
- Upgrade the hardware: Replace plastic stakes with 12-inch steel rebar.
- Switch the string: Use 550 paracord instead of the included thin twine.
- Elevate the blower: Use bricks to keep the intake away from snow and debris.
- Watch the weather: Deflate the unit if wind speeds are projected to exceed 20 mph.
- Check the amps: Ensure your circuit can handle the 200-300 watt draw of a high-power blower.
Taking the next steps
Before you click "buy" on that massive holiday centerpiece, take a tape measure out to your yard. Actually visualize twenty feet. That is taller than most gutters on a standard two-story home. Ensure you have a clear "fall zone" where the Santa won't hit power lines, sharp tree branches, or your neighbor's fence if a tether fails. Once you have the space cleared, invest in a heavy-duty outdoor timer rated for at least 15 amps. Setting the Santa to automatically deflate during the overnight hours will save you a fortune on your electric bill and extend the life of the blower motor significantly.
Dry the fabric, secure the base, and keep the air flowing. That’s how you keep the biggest Santa on the block standing tall until New Year's Day.
