How many people can Facebook ads reach in Jersey and Guernsey?
Meta's advertising tools put Facebook ad reach at 54,400 people in Jersey (52% of the population) and 38,200 in Guernsey (59%), with Instagram at 44,100 and 25,400 respectively, as reported by DataReportal's Digital 2026 reports (late 2025). Those are the most people an ad could reach on each island before you narrow it by age, location or interest.
How this is worked out
The tool takes the island figure for the platform you choose and multiplies it by the share of the island you think could be your customer. For Facebook and Instagram together it starts from the larger of the two figures, because the same people often use both and Meta does not publish a combined island total. Results are rounded because the source figures are themselves estimates. Nothing you type is stored.
What to do with the number
A small audience is normal on the islands and is not a reason to avoid ads: it means the same people see your ads more often, so creative needs refreshing more often. Our guide to Facebook and Instagram reach in Jersey and Guernsey explains the figures in more depth, and the budget planner and break-even calculator turn your audience into a budget and a target cost per lead.
