Surfaces are terrain features in the Splatoon series. There are two types: inkable and un-inkable. Inkable surfaces comprise most of each stage's terrain, being counted towards players' turf counts. Un-inkable surfaces are less common, being used as barriers or stage boundaries or to make an area more difficult to maneuver in.
Inkable Surfaces are terrain features that can be covered in ink. Ink shot or flung with will appear on these surfaces, allowing Inklings and Octolings to swim across them. Most inkable surfaces behave identically, despite varying appearances.
Concrete is one of the main surfaces found in Splatoon, being featured heavily in most stages. It appears as a uniform black or gray surface, with few noticeable differences in a single area.
Brick is used frequently in Octo Valley and various single-player missions. It can also be found in Bluefin Depot. Like the name suggests, it appears as a common red or orange brick pattern. These bricks are often broken or cracked.
Soil is the main surface in Kelp Dome. It appears just like flat soil, with a brown appearance and the presence of a few weeds.
Grass is a type of surface that is primarily green or blue, often decorated with flowers and other small plants. It appears very frequently in Octo Valley, and significantly less frequently in Urchin Underpass, Blackbelly Skatepark and Flounder Heights.
Paper appears primarily in Walleye Warehouse on top of crates. They can be inked and swam on.
Signs are plastic and metal signs that appear throughout Octo Valley, Inkopolis, and in the training area behind Ammo Knights. They tend to appear vertically, displaying various messages and graphics. They act like normal surfaces.
Although trees are inkable, Inklings cannot swim up them as their leaves provide no support. They appear in Octo Valley, Inkopolis Plaza, Flounder Heights, and Urchin Underpass, but serve practically no purpose other than an obstacle.
Cicadas can be heard singing in the trees in Flounder Heights, unlike the trees found in other parts of the game.

Grates are semi-solid surfaces that allow the player to pass through, intentionally or not, while in squid or octopus form. The grates themselves, however, cannot be covered in ink. Examples of grates can be found in maps such as Bluefin Depot and Kelp Dome, to name a few.
- Main article: Water
Water is a common liquid; it is less a surface and more a hazard, as it cannot be stood upon, much less inked. Water is deadly to the touch for Inklings and Octolings. Water can be found in maps such as Camp Triggerfish and Arowana Mall, in addition to various locations in Octo Valley.
- Main article: Bumper
Bumpers can be found in multiplayer and Octo Valley in various locations. Their rubbery, cushiony qualities prevent the barriers from taking any ink whatsoever, making them excellent for cover. Be warned, however, as a weapon with an arc (such as a Slosher) can go over the top of the bumpers and still strike any vulnerable players behind. Bumpers can be found in stages such as Kelp Dome and Moray Towers, as well as various locations in Octo Valley.
