The holes seem to match 16 stud spacing but no two door frames and no two placements will be the same.
Stud spacing above sliding door.
I m also looking to change our laundry door to a sliding door to gain some space.
Stud spacing is 16 apart.
Above windows and doors are doubled up studs called headers.
The common way of building a window frame is to use what are called jack studs in addition to the cripple studs.
For double doors locate the studs on both sides of the door opening.
But there are also horizontal framing members located above and below door and window openings.
The full length stud on each side of a door or window is called a king stud.
Use the stud finder to locate and mark the studs above the door.
A header is a piece of framing installed horizontally directly above the door or window opening and extending to the king stud on each side of the opening.
The king studs nailed into the end of each header and the trimmers that butt just under the header combine to create a sturdy vertical support column.
Not just pretty because it is anchored into the studs.
Together the headers king studs and trimmers act as a system that transfers weight from above down and around the window and door openings to the floor and foundation below.
To center this perfectly over a door frame the framing stud is usually centered above the door.
Butt these studs up against the inside of the king studs and above the sill.
When hunting for wall studs usually the goal is vertical studs.
The holes on the door track are 12 apart.

I centered this above a door opening that has two sliding doors that meet in the middle.

For single doors start about three or four inches up on the hinge side of the door opening and continue for the length of the backer board.
Find wall studs above and below doors and windows.
