Seating wedding guests who don't know anyone
Every guest list has a handful of people who arrive not knowing a soul. A few deliberate seating decisions can turn that around before the first course arrives.
Who are the "solo" guests?
They might be a work colleague of one partner, a distant relative who lives far away, or a plus-one whose partner will be tied up with wedding party duties. What they have in common: they can't anchor themselves to a group they already know.
Seat them near naturally sociable people
Placing a solo guest next to another introvert doesn't help either of them. Look for guests who are known to draw others in — warm, curious people who won't let a conversation die. One or two of those at the same table changes the dynamic for everyone.
Connect through shared context
If you can find any thin connection — same profession, same hometown, children of a similar age — use it. Even a vague link gives people something to open with. You don't need to engineer deep friendships, just a starting point.
Avoid grouping all the solo guests together
Seating all the "unknown" guests at one table seems tidy but often backfires. A table of people who know no-one has no social anchor and nobody to set the tone. Mix at least one familiar cluster into any table that includes solo guests.

Consider the table size
Larger tables (ten or more) can feel anonymous — there's less pressure to talk across the whole table, but it's easier to get stranded in a corner. Smaller tables of six or eight make it harder to disengage but easier to feel included.
Solo guests are one thread in the wider task of how to seat wedding guests across every table.
