Does adding a wifi enabled switch impact wiring in box capacity?

[Fsmith527]

Hi all: total diyer here. First post. I have a four gang switch box (15 amp). I want to replace three standard switches with three wifi enabled switches but am concerned that I have to put in an increased sized four gang box due to capacity limitations on this standard size four gang box that is presently in there. I think the box size that is in there is only 60 cubic inches or less. Would adding the connections for three wifi enabled switches exceed the capacity? I can purchase a four gang box with a 71 cubic inch capacity but it makes the job a lot bigger than I was planning. I’m still learning how to ensure I don’t exceed the capacity of a box based on the wiring. I’ve included some pics if that helps. Thanks in advance for the your help and kindness! Cheers.
