4-1/4" and some larger wall tiles have bumps cast in that act as spacers. Unless you want a larger gap, no additional spacers are needed.
Whether your particular tile has them is uncertain. They're often necessary to prevent sagging with heavier tile while the mortar or mastic sets.

Subway Tile - spacers | DIY Home Improvement Forum
A word about spacers--Go to 'Floor and Decor" on 59--they have flat horse shoe shaped spacers---much easier to use than the crosses--especially for subway tile--because they are typically set in a soldier course or running bond--meaning the crosses are useless. ...

I like the look of 1/16” (1.5mm), but the Internet is telling me 2-3mm to allow for stress movement. The current shower uses 4x4 tile with shower pan and the grout lines look like they range from 1/32 to 1/16”. There are vertical stress cracks in a couple of the lower tiles which I assume ...

r/Tile on Reddit: Subway tile backsplash - spacer confusion
January 4, 2024 -
I’m seeing conflicting guidance on what spacing to use with these tiles; and if spacers are required.
The sides have a slight bevel such that the tops are just under 1/16” apart. In my testing with 1/16” spacers, the grout line ends up at 1/8” which is visually much thicker than I prefer. I’m trying to minimize the grout lines as much as possible.
What would you do in this case?
**Tiles are 2x8 inches. This will be a kitchen backsplash

i definitely wouldnt use spacers because like you said would open to much. the bottom part of tile is done like that for a reason, its a built in spacer, so you can just stack them and use an unsanded grout. i personally would use wedges, the ones i have are super fine at the ends and use them just to basically keep everything straight, so it would open them up slightly as long as you dont put the wedge all the way to the back of tiles. in the end it would end up slightly less than 1/16 which would look great, but would still use an unsanded grout unless you opened them up to 1/16. 1/16 or slightly thinner is my choice using thin wedges, but dont use spacers

I use wedges to open up the joint just a tiny bit and keep the tiles level. I try to never butt joint the tiles so that I can avoid possible cracking, but that's just how I was taught long ago.

We aren’t so quick, so we chose to “back butter” the tiles, which means we applied the adhesive directly onto the back of the tiles individually as we went. That way we weren’t rushed and we could give each tile plenty of attention. Like I mentioned earlier in the post… we didn’t use spacers.

r/Tile on Reddit: Built in tile spacers?
March 5, 2022 -
I recently purchased some Daltile subway tiles from home Depot. I'm realizing now that they have "built in lugs" to space them 1/16" apart without having to use separate spacers. Has any one used tiles like this? I want the 1/16 grout lines, but am worried that the grout may fall out as it can't penatrate as deep between the tiles as standard spacers. I plan on using Custom Fusion Pro grout as this is for a shower.
Thanks in advance!

I don't use fusion. It's for diy people because it's premixed. Just use that mapei ultracolor that everyone likes. You shouldn't dabble in epoxy if you are a first timer.

I am also considering the HD Daltile Restore 3 x 6 subway tiles for my tub/shower surround and have the exact same concerns about grout penetration. Especially because the continuous lugs have glaze on them and I'm worried the grout will not stick inside the shallow channel and chip out. I was planning on using regular unsanded grout. How did your project turn out? Did you end up going with the HD Daltile, did you butt them together, what grout did you use and how is it holding up? Thanks for your reply!
