A 4 in (10 cm) backsplash is the minimum standard size for a backsplash so you don’t damage walls or get them dirty. Some countertops come with built-in backsplashes that are already attached or connected with an adhesive. Apply a bead of caulk on the seam where your backsplash and counter meet so spills don’t leak underneath it. Add another line of caulk on top of your backsplash where it touches the wall.
Under-cabinet backsplashes work best in larger kitchens so you don’t have to spend as much on tiles. You may need to cut the tiles so they can fit properly between your counters and cabinets. Use subway tiles for your backsplash for an affordable but stylish option.
Another area to consider lining your tiles up with is the bottom of your range hood. If the top edge of your tiles forms a new horizontal line in your kitchen, it may make the room look a little disjointed. Remember to grout your tile to fill the gaps between them to prevent spills and splashes from reaching the wall.
Full backsplashes work best in smaller kitchens with lower ceilings since you don’t have to account for as many tiles. If you want to leave some of your wall exposed below your ceiling, end your backsplash so it lines up with the top edge of your upper cabinets instead. Try peel-and-stick tiles to make a full backsplash without breaking the bank.
Avoid extending your backsplash past the edges of your countertops or cabinets since the tiles make look a little awkward without anything above or below them. Adding a thin vertical piece of metal or plastic trim can help you frame out where to place your tiles and give your backsplash a clean edge.
Try taping or tracing tiles in the pattern you want to try to get a better idea of what it looks like on your wall. You don’t need to use any trim pieces if you’re planning a tapered transition to your wall.
If there’s an L-shaped counter in the corner, then it’s okay to continue your backsplash onto the next wall.
Only placing tiles behind your stove is perfect if you don’t have a lot of DIY experience since you don’t have as much area to cover. [10] X Research source
Alternatively, use metal tile trim or pencil tiles for a low-profile way to add a clean edge. You only need to add trim pieces if you don’t want the raw edge of the tile showing.
