About this site
How this site checks specs, prices and room math
Every room figure on this site is quoted from the maker’s own page with the date it was copied, every price comes from a shop page with the day it was checked, and the swing height is this site’s estimate from a model, not a measurement. No launch monitor is tested here.

Where numbers come from
Maker pages, shop pages, dates
Every number on a page can be traced to a dated source.
A room figure is stored with the exact sentence the maker wrote, the address of the page and the day the copy was made. When a maker publishes two different figures on two of its own pages, both are shown and the calculator uses the stricter one.
A price is stored with the shop, the product page and the day it was checked. A price that differs from the maker price by more than half is set aside for a manual check and is not shown.

The swing model
How the ceiling estimate works
The swing height is an estimate. It scales the club head’s highest point with your height and the club, and it is calibrated on three maker statements: SkyTrak’s 9 ft for a standard golfer, and Trackman’s and Foresight’s 10 ft for a comfortable swing. Foresight’s 8.5 ft for irons only matches the model for a 5′9″ golfer with a 7-iron.
Swings differ. Check a new room with slow swings first; ceiling protection and ball rebound are the owner’s decision.
The model is calibrated on maker figures, not measured swings.
Shoulder height
0.818 × heightBody proportions from the biomechanics literature.
Reach
0.386 × height + clubArm to the hands plus the club: driver 45.75″, 7-iron 37″.
Swing top
shoulder + 0.698 × reach + matSet so a 5′9″ golfer with a driver on a 1″ mat reaches 9 ft, SkyTrak’s figure for a standard golfer.
Comfortable
+ 12″Trackman and Foresight call 10 ft the practical minimum for a comfortable full swing.
Depth and width
How depth and width are counted
Where a maker is silent, the page says so.
Depth runs from the wall behind the screen to the back wall. Width is counted for the swing itself and then checked against the maker’s own width figure.
Depth
1 ft behind the screen (Foresight) + the maker’s ball-to-screen distance + the unit behind the ball and 1 ft, or about 5 ft for the backswing when nothing sits behind the golfer.
Width
The golfer side of the ball needs 6.5 ft and the other side 3.5 ft for a 5′9″ golfer (from Garmin’s 10 ft and 13 ft), scaled by reach; right- and left-handed players together need the golfer side twice.
Maker minimums
When a maker publishes a total depth, a minimum room or a minimum width, the stricter of that figure and the model is used.
No maker figures
Square Golf Home Edition, Square Golf Omni, Blue Tees Rainmaker: their makers publish no room figures on the pages checked; the calculator assumes 8 ft from the ball to the screen as the minimum and 10 ft as comfortable.
Fits, tight, does not fit
What the three results mean
The result never sets a limit softer than the maker’s own figure. A “tight” result is a reason to measure again and to test with slow swings.
Projector placement
How projector placement is worked out
The projector calculator applies BenQ’s formulas to your screen, picture shape and throw ratio, and compares the throw distance with the ball position of the chosen monitor.
Throw distance
throw ratio × picture widthBenQ’s formula.
4:3 picture from a 16:9 projector
throw ratio × picture height ÷ 0.5625BenQ’s formula for the square golf picture.
Where it should land
2–3 ft behind the hitting areaBenQ’s advice.
Not counted
What the totals leave out
Cost totals add the monitor, the screen or enclosure, the mat, the projector and the plan over the years you choose. Installation, a PC, flooring, tax and shipping are left out.
Installation
Not in the cost totals.
A PC
Most course software needs one.
Flooring, padding, lighting
Not in the totals.
Tax and shipping

How texts are written
Texts and checks
The texts are written by AI from the saved facts of each page. Code then checks every draft: each number must appear in those facts, claims must name the maker or the shop, and drafts with superlatives, sales language or claims of testing are rejected. A page that fails is not published.
If a figure is missing, the text says the maker does not publish it.
Where to check the price
