Build a classroom or office seating chart and print or save it as PDF entirely in your browser — for anyone who wants a free seating chart maker instead of building one by hand in Excel, or who wants to shuffle seats at random. Enter one name per line and set the number of rows and columns; names fill the seat grid in reading order (top-left to the right, row by row). When you have fewer names than seats, the extras are shown as empty (dashed) seats. Click "Shuffle seats" to randomly reorder the names and re-place them — handy as a random seat picker, used as many times as you like. Turn on "Show front bar" to add a label above the grid for the board / front of the room (the label is free text, defaulting to "Board"). Choose "View from front (mirror)" to flip the columns left-to-right, matching how the room looks from the front. Turn on "Seat numbers" to print a running number in each seat's corner. Add a note below the grid and it prints with the chart. Click "Print / Save PDF" to open the print dialog at A4 actual size, then print or choose "Save as PDF". Your names are never uploaded or stored — everything happens on your device — and only the rows, columns, front-bar / mirror / seat-number toggles and accent color are remembered (names, title, front label and note are not saved).
