The 2018 Honda Civic offers roughly 97–98 cubic feet of passenger space in the sedan and about 15.1 cubic feet of trunk space. Hatchback variants increase cargo capacity substantially, while maintaining similar front-seat comfort. These figures come from Honda’s official specifications for the 2018 Civic models.
This article breaks down interior size by body style and dimension, including passenger space, headroom, legroom, shoulder room, and cargo capacity. It covers both the sedan and hatchback versions so you can gauge how interior size translates to real-world seating and storage needs.
Interior space by body style
Below are the key interior measurements for the two main 2018 Civic body styles available in many markets: the sedan and the hatchback. Each list highlights how much room you get for people and cargo.
Sedan interior: passenger space and trunk
Before diving into the numbers, note that these figures reflect typical EPA-era spec measurements for the 2018 Civic Sedan and are representative across common trim levels.
- Passenger volume: approximately 97.8 cubic feet
- Trunk space: about 15.1 cubic feet
- Front headroom: around 39.0 inches
- Rear headroom: around 37.0–37.5 inches
- Front legroom: about 42.3 inches
- Rear legroom: roughly 37.0 inches
- Front shoulder room: roughly 57.0 inches
- Rear shoulder room: around 54.8 inches
The sedan’s interior emphasizes a compact-car balance: comfortable front seating with ample trunk space for its class, but rear passenger space is a tad tighter on longer trips.
Hatchback interior: cargo versatility and passenger space
Hatchback measurements reflect the model’s emphasis on cargo versatility while preserving passenger comfort similar to the sedan.
- Passenger volume: approximately 97.8 cubic feet (similar to the sedan)
- Cargo space behind rear seats: about 25.7 cubic feet
- Cargo space with rear seats folded: up to around 46.0–46.2 cubic feet
- Front headroom: around 39.0 inches
- Rear headroom: around 37.0 inches
- Front legroom: about 42.0 inches
- Rear legroom: roughly 37.0 inches
- Front shoulder room: roughly 57.0 inches
- Rear shoulder room: around 54.8 inches
The hatchback’s cargo figures show a meaningful improvement in storage capacity compared with the sedan, especially when rear seats are folded, making it a more flexible choice for hauling larger items.
How these numbers translate to everyday use
In daily driving, the Civic’s interior dimensions translate to easy five-person seating with comfortable front comfort and adequate rear space for adults on shorter trips. The hatchback’s larger cargo area proves useful for groceries, sports gear, or weekend bags, while still accommodating adult passengers in the rear seats.
Other considerations
Interior size can vary slightly by trim and optional seating configurations, but the general measurements above reflect the 2018 Civic lineup. If you plan to maximize cargo or routinely seat taller passengers in the back, the hatchback offers the most versatility, while the sedan remains a solid all-around compact with a traditional trunk.
Summary
The 2018 Honda Civic provides nearly 98 cubic feet of passenger space in both sedan and hatchback forms, with the sedan delivering 15.1 cubic feet of trunk capacity and the hatchback offering significantly more cargo space behind the rear seats (about 25.7 cubic feet) and up to roughly 46 cubic feet with seats folded. Front seating is comfortable, and rear space is adequate for adult passengers on shorter trips in both body styles. overall, the interior size aligns with typical compact-car expectations, while the hatchback adds notable cargo versatility.
