Seating charts are a great alternative to escort cards. Rather than having a separate card for each guest, a seating chart allows you to prominently display the seating assignment for your reception.
They also work well when used with place cards; the seating chart would direct your guest to their table, and the place card (which would be placed at table) will mark their seat.
The names can be arranged alphabetically or by table, and a list of the members of your bridal party could also be included.
Seating chart sizes can be changed to accommodate your needs, as long as the design retains its orientation and overall shape.
Because of the large size of these designs, using a professional printer is necessary. Generally, you'll have the design printed as a poster, then mount on foam board or have the seating chart framed.
Plan ahead to save yourself the stress of putting together your seating plan at the last minute. Seating charts often end up being a last minute item, so make sure to check with your printer for their turn around times (some can have the chart ready as quickly as 1-2 hours; other printers may require up to a week to have the design ready)
