Landscape Lighting Transformer Planner
Use this landscape lighting transformer planner to group the yard into real zones, mix fixture wattages, estimate wire distance, and get to a more realistic transformer size before you buy the wrong equipment.
It is built for homeowners who need something more useful than rough fixture counts. Fill out the zones, review the totals, and save a clean planning summary for your own purchase decision or an installer conversation.
Build the plan first, then review the sizing result
Start with the zones, add the fixtures, then review the recommendation below.
Zone 1
Add the main run distance and the fixtures that belong in this zone.
This run looks fairly manageable for a typical residential zone, but still confirm wire gauge against the final layout.
Planner Result
Recommended transformer range
Once the zones are filled out, use this section to review the totals, pressure-test your reserve capacity, and save a clean PDF summary.
Connected load
38 W
Planned load
43.7 W
Recommended minimum
52.4 W
Suggested transformer
75 W
That keeps the planned load around 58.3% of the selected transformer before any future additions.
Front Walk
This run looks fairly manageable for a typical residential zone, but still confirm wire gauge against the final layout.
Practical note
This planner is meant to help homeowners structure a better purchasing and layout decision. It is not a substitute for final electrical judgment on wire gauge, transformer taps, or voltage drop in long or heavily loaded runs.
Next steps

If you are using the planner seriously, these are the next pages worth opening before you buy hardware.
Read the transformer sizing guide
Use the homeowner guide if you want the reasoning behind the planner totals and reserve-capacity logic.
Check voltage drop
Pressure-test longer runs after you estimate total load and wire distance in the planner.
Compare wire gauge options
Use the gauge calculator when you need a cleaner starting point for wire size on residential runs.
