Side Entry vs End Entry on Larger Garages: The Door Placement Decision

Larger garages offer plenty of room for vehicles, equipment, storage, workshops, and other uses, but that extra space also makes door placement an important design decision. The location of your garage doors can affect how easily you enter and exit the building, how you arrange the interior, and how well the structure fits on your property.

For some properties, an end-entry garage provides the most direct access from a driveway and makes efficient use of the available space. On other sites, a side-entry layout may create a better traffic flow, preserve more usable wall space, or make it easier to organize multiple vehicles and work areas. The larger the garage becomes, the more these considerations can influence the overall functionality of the building.

If you're looking at an open carport, our post on side entry versus end entry carports covers the driveway approach side of this. What follows is the enclosed building version, where the walls change the math.

Key highlights

• The gable end is the wall with the peak. The eave side is the long wall where the roof edge runs.
• A roll-up door needs roughly 2 feet of wall above the opening for the roll, which caps door height on the eave side.
• A 9-foot sidewall generally tops out at a 7-foot roll-up door. Want an 8-foot door, plan on 10 feet of sidewall.
• Putting the door on the gable end lets you use the peak, so you can go taller without raising the whole building.
• End entry preserves your longest wall for benches, racking, and shelving. Side entry breaks that wall up.
• Door placement affects price, so ask your rep to quote it both ways before you decide.
• Water sheds off the eave sides, which puts a side-entry door under the drip line.

First, know which wall is which

The gable end is the wall with the triangle shaped peak. On a 20x25 building, the gable ends are the two 20-foot walls.

The eave side is the long wall where the roof edge comes down. On that same building, the eave sides are the 25-foot walls. Roof panels shed water off these sides, and you get about 6 inches of overhang along them.

So when somebody asks for "side entry," they mean a door in an eave wall. "End entry" means a door in a gable wall. On most buildings the gable end is the shorter dimension, though not always, and that's exactly why we ask instead of assuming.

The rule that decides most of this

A roll-up door doesn't disappear into the ceiling like a residential sectional door. It rolls up into a drum that sits above the opening, and that drum needs somewhere to live. Figure on about 2 feet of wall above the door.

What it means on the eave side

On an eave wall, the height is based on your sidewall height. Whatever the wall measures is your ceiling for the door plus the drum.

Run the numbers:

• 9-foot sidewall gets you a 7-foot door
• 10-foot sidewall gets you an 8-foot door
• 12-foot sidewall gets you a 10-foot door
• 14-foot sidewall gets you a 12-foot door

Our own buildings show the pattern. The 18x30x9 side entry garage runs two 8-by-7 roll-up doors on the side, because 9 feet of wall is what it has to work with. Step up to the 30x40x11 side entry garage and the added sidewall height supports a 12-by-10 framed opening.

If you drive a lifted truck, a dually, or anything with a rack on top, run your numbers before committing to side entry. A 7-foot opening sounds fine until you're folding mirrors and holding your breath.

What the gable end gives you

On a gable wall the peak works for you. The wall keeps climbing above your sidewall height toward the ridge, which leaves room above the opening that an eave wall doesn't have.

On a 20-foot-wide building with a standard pitch, the peak sits a few feet above the sidewall, so a door centered in that gable wall can often go a foot or two taller than the same building would allow on the side.

That's why RV garages and equipment buildings load from the end. When you need a 12 or 14-foot door, the gable end is usually the only place to put it without raising the whole building.

Our guide on how tall metal buildings can go covers what each sidewall height opens up.

Typical price impact	Varies, ask for both	Varies, ask for both

What you give up in wall space

Your eave walls are your longest walls. On a 24x35, that's two 35-foot runs of uninterrupted steel, and that's where shelving, racking, a bench, a tool chest, and a compressor all end up.

Cut a 12-foot opening into one of those walls and you've split it into two shorter runs, neither of which may be long enough for what you planned. Add a second door and it fragments further.

Water, overhang, and the drip line

Roof panels on a vertical roof run from the peak down to the eaves. Water goes where the panels point, which means it comes off the eave sides. We build with about 6 inches of overhang along those eave sides and can go up to a foot, which throws the drip line out past the wall.

Still, a side-entry door sits under where the water comes off. Heavy rain means standing in the runoff while you open it, and in freezing weather that's where ice forms. Neither is a dealbreaker, and thousands of side-entry buildings work fine every day, but it's worth knowing so you can plan for it.

A gable-end door sits out of the drainage path entirely. On the regular and boxed eave roof styles you also pick up about 6 inches of overhang front and back, which gives you a little cover at the door. If you're in snow country, think about where sliding snow lands. It comes off the eaves, and you'd rather it not pile against the door you use every day.

Which layout fits your situation

Homeowners and hobby shops

Go with what your property allows. If the driveway runs alongside the building, side entry saves you a turn and a lot of backing. Just check your door height first. If you're parking a standard car or half-ton truck under a 10 or 12-foot sidewall, side entry works fine.

Contractors and tradesmen

End entry is the best option most of the time. You need wall space more than you need a shorter approach, and you're usually running taller vehicles with racks or ladders. If you want both, plenty of our customers put a large door on the gable end for the truck and a walk-in door on the eave side for daily foot traffic. This configuration offers the best of both without sacrificing the long walls.

Farmers and equipment storage

This depends on what's going in. Tractors, combines, and anything with a loader want the gable end for height and a straight shot in.

For lower equipment like UTVs, mowers, and implements, side entry on a long building gives you multiple bays and you're not pulling everything out to reach the machine in back. Our 24x35x11 side entry garage is a good look at how that lays out.

Anyone storing an RV or a camper

End entry is the best option. You need the height and you need the straight approach, and the gable end is the only wall that gives you both.

What about the cost difference

Door placement affects price, usually by a modest amount. It comes down to how the framing gets reinforced around the opening and which wall it lands in. The exact figure depends on your building size, sidewall height, opening size, and what your local wind and snow requirements call for, since we engineer every building to your address.

You’ll also want to decide whether you want a roll-up door or a framed opening you’ll fill with a third-party sectional door later. That choice affects your headroom math too, and our post on frame-out versus factory roll-up doors walks through both.

Decide before the slab gets poured

Door placement is one of those things that has to be right the first time. Moving a garage door after the building is up means cutting into finished framing and paneling, and at that point you're paying for work you already paid for once.

It also affects your concrete. Where the door goes determines your apron, your approach, and how you grade so water runs away from the opening instead of into it.

So you’ll want to sort it out early. Tell us what's going inside, how tall it is, how you'll approach the building, and what you want along the walls. That's usually enough for us to tell you which wall the door belongs in.

Frequently asked questions

What's the difference between side entry and end entry on a metal garage?

Side entry puts the door in an eave wall, which is one of the long walls where the roof edge runs. End entry puts it in a gable wall, the wall with the peak. The main practical difference is potential door height.

Why can't I get a taller door on the side of my garage?

A roll-up door rolls into a drum above the opening, and that drum needs roughly 2 feet of wall above the door. On an eave wall your total height is the sidewall height, so a 9-foot sidewall generally supports a 7-foot door. To go taller on the side, raise the sidewall.

Is side entry or end entry more expensive?

Placement affects price, usually by a modest amount that depends on your building size, opening size, and local engineering requirements. Ask your rep to quote both layouts so you can compare the actual figures for your build.

Which is better for an RV garage?

End entry. RVs need height, and the gable end is where the peak gives you room above the door. A straight-on approach also beats trying to swing a 35-foot motorhome into a side opening.

Can I put doors on both the side and the end?

Yes. Plenty of buildings run a large door on the gable end and a walk-in or smaller roll-up on the eave side. Just tell us at quote time, since each opening changes how the frame is built around it.

Does the door go in the center of the wall?

It doesn't have to. Centered is common on gable ends because that's where the peak is tallest, which maximizes your door height. On eave walls you can place doors wherever your layout calls for, though we'll space them so there's enough framing between openings.

Can I move the garage door after installation?

No, not practically. Relocating a door means cutting into finished framing and paneling and rebuilding the opening. Placement is a decision you make at quote time, along with width, length, and sidewall height.

Making the call

Start with the tallest thing going through the door and add 2 feet for the roll. If that number is taller than your planned sidewall, your door belongs on the gable end or your sidewall needs to come up.

Then look at what you want along the walls inside. If you're building a working shop, protecting those long eave walls is usually worth giving up the convenient approach.
