How to Build a Golf Simulator

A golf simulator build fails in the planning order, not in the shopping. Buy the projector first and the room may not fit its throw. Buy the monitor first and the room may not fit its kind. This is the order that cannot strand you, and every step is a tool on this site.

A golfer mid-swing in front of a home golf simulator enclosure and screen — What you are building: an enclosure, a screen and a clear swing space, in that order.

Step 1: Measure the room, honestly

Length, width, and the ceiling height where you will actually swing, under any beam, duct or door opener. Then the room size calculator gives a verdict per monitor class, because the same room passes for one class and fails for another. If no class fits, this is the cheapest moment to learn it.

Step 2: Let the room pick the monitor class

Radar behind the ball, camera beside it, or overhead. The launch monitor finder rules out the classes your space cannot hold, then ranks what is left by your budget and whether you need measured club data or real putting. Class first, model second: models change every year, the class decision is the one your room locks in.

Step 3: Size the screen to the wall

The image is sized by your usable wall and your aspect ratio, and the screen class follows from that, not the other way round. The screen size calculator also tells you which side of the wall limits you, and what stepping down one class costs. Remember the gap behind the screen, 6 to 16 inches by the screen makers' manuals, comes out of your room depth.

Step 4: Place the projector, check your shadow

Throw ratio times image width is the mounting distance. The projector calculator adds the check most builds skip: if the lens ends up behind your hitting position, your body is in the picture. Short throw exists precisely to keep the projector in front of the swing.

Step 5: Budget by phase, then buy in phase order

The cost calculator prices each component by tier. Phase it: monitor, screen and mat first (you are hitting balls), projector and computer second (it becomes immersive), paid software third (it becomes complete). The setup planner runs all five steps in one form and prints the phased list.

Step 6: The tape test, then the first session

Before the first full swing, the taped-wall test from the ceiling guide: slow driver swings under a mark at your lowest obstruction, for every golfer who will play. Set the monitor at its maker's distance, level and square to the target line, and expect the first session to be calibration, not a personal best. A simulator built in this order has no expensive surprises left in it.
