An inline booth is a trade show exhibit space positioned in a row between other exhibitors, with only one side open to the aisle. It’s the most common and most affordable booth type at exhibitions, and the standard size in the United States is 10 feet wide by 10 feet deep (100 square feet). If you’ve walked through a trade show and seen a long row of exhibitors lined up side by side, each one of those individual spaces is an inline booth.
How an Inline Booth Is Arranged
The defining feature of an inline booth is that it has one open side facing the aisle and shares walls with neighbors on the left and right. The back wall faces away from attendee traffic. This layout creates a natural “storefront” feel where visitors approach from a single direction.
U.S. trade show floors are typically designed in 10-foot increments, making the 10-by-10-foot booth the building block of most floor plans. You can purchase multiple inline spaces side by side to create a larger footprint (20 by 10, 30 by 10, and so on), but the single 10-by-10 unit is standard for first-time exhibitors, smaller companies, and anyone testing a new show.
Height Restrictions and Sightline Rules
Because inline booths sit in a row, strict height rules keep one exhibitor from blocking the view of the booth next door. The International Association of Exhibitions and Events (IAEE) guidelines, which most U.S. shows follow, split the booth into two zones:
- Back half (rear 5 feet): Displays, walls, and signage can go up to 8 feet tall.
- Front half (forward 5 feet toward the aisle): Everything must stay at or below 4 feet, roughly waist height.
The 4-foot rule in the front half exists so attendees walking the aisle can see neighboring exhibitors without a tall display blocking their line of sight. If you combine three or more inline spaces into one larger exhibit, that front-half restriction relaxes a bit. In that case, the 4-foot limit only applies to the portions within 10 feet of an adjoining booth rather than the entire front half of your expanded space.
Individual shows may tweak these numbers, so always check your exhibitor manual. But 8 feet in the back and 4 feet in the front is the baseline you can expect.
How Inline Compares to Other Booth Types
Trade shows offer several booth configurations, and the key difference between them is how many sides are open to foot traffic.
- Inline (linear): One open side. Most affordable, best for smaller budgets.
- Corner: Two open sides, sitting at the end of a row where two aisles meet. More visibility than a standard inline at a moderate price bump.
- Peninsula: Three open sides, sharing only one wall with a neighbor. Creates a semi-island presence without the full island price tag.
- Island: Four open sides, completely detached from other exhibitors. The premium option with maximum visibility and the highest cost.
Inline booths cost the least in both floor space rental and build-out because you only need to design one “face” for attendees. You don’t need signage or displays on three or four sides, and the smaller footprint keeps shipping, installation, and material costs down.
Making the Most of a Single Open Side
With only one direction to attract visitors, your design choices matter more in an inline booth than in a larger, multi-sided space. A few strategies make a measurable difference.
Use vertical space wisely. Your tallest, most eye-catching graphics belong on the back wall where you have that full 8 feet of height. Keep text and key messaging above waist level. Anything placed low will be hidden by furniture, product displays, and the people standing in your booth. Bold, high-resolution images and simple text are easier to read from the aisle than detailed copy.
Light your space deliberately. Spotlights and backlighting help your booth stand out from neighbors who rely on the convention hall’s overhead fluorescents. Many modern display systems have backlighting built in. Keep in mind that you’ll need to order electrical service from the venue’s official provider, which is an additional cost to budget for.
Think about floor plan placement. When you’re selecting your booth location, spots near main entrances or at the beginning of an aisle tend to get more foot traffic. Attendees are freshest and most attentive at the start of their walk through a hall. If booth selection is first-come, first-served, registering early can help you land a higher-traffic position.
Keep the front half open and inviting. Since everything in the forward 5 feet must stay below 4 feet anyway, use that zone for a small counter, a demo table, or a product display that draws people in rather than creating a barrier. An open, uncluttered entrance makes visitors more likely to step inside rather than walk past.
Who Typically Uses Inline Booths
Inline booths are the workhorse of trade show exhibiting. They’re the go-to choice for companies attending a show for the first time, startups with limited budgets, and established businesses that exhibit at dozens of shows a year and need a setup that’s easy to ship and install. Many exhibitors start with a single 10-by-10 inline space and upgrade to a larger configuration or a different booth type as their trade show program grows and they can justify the higher cost.
Even with the constraints of one open side and strict height limits, a well-designed inline booth can generate strong leads. The format forces you to be concise with your messaging and intentional with your layout, which often results in a cleaner, more focused visitor experience than a sprawling island booth with no clear focal point.
