A practical step-by-step guide to arranging an A3 letter board with 50mm Alu Numbers, from planning your layout to keeping the display fresh.
Quick answer
Treat your A3 letter board as a small poster: decide on one focal line, use 50mm Alu Numbers only where they earn their space, and leave breathing room around every character. The steps below walk you through planning, placing, and refreshing the layout so it looks intentional rather than crowded.
Why 50mm numbers change the layout
At 50mm tall, Alu Numbers are statement pieces, not fine print. On an A3 board they take up roughly the height of two lines of smaller letters, so a single number can dominate the composition. That is useful for a date display or a countdown, but it means you cannot treat numbers as an afterthought.
The original Arne Jacobsen vintage typography gives each piece a sharp, graphic outline. The wire-and-laser-cut production makes the shapes precise, so alignment matters: a number that sits slightly off-centre is more noticeable than with softer, rounded characters.
When a number-led layout works better than a quote
A quote-led board relies on many small letters and tight spacing. A number-led board, by contrast, uses fewer elements and more negative space. If your goal is a date display, a birthday countdown, or a menu with prices, start with the number and build the words around it.
For everyday decor, reserve 50mm numbers for one or two key figures and keep the rest of the board in letters. This prevents the board from looking like a calendar and keeps the typography readable from across the room.
Step-by-step: arranging your A3 board with 50mm numbers
- Choose the board's job: Decide whether the board will show a date, a menu, a quote, or a countdown. Write that purpose down before you touch a single character. Common mistake: starting with a pile of letters and hoping a message emerges. If the purpose changes weekly, pick a layout template you can repeat.
- Map the focal point: Place the 50mm number or numbers first, slightly above the vertical centre of the board. Then sketch where the supporting words will sit around them. Checkpoint: step back three paces; the number should be the first thing you see. One dominant number is stronger than three competing ones.
- Set the spacing rhythm: Leave at least one character-width of empty space between the number and any adjacent letter. Keep line gaps consistent: if you use two lines, make the gap between them roughly half the height of a 50mm number. Common mistake: crowding the number to fit more words. Empty space is part of the design, not wasted board.
- Align to a baseline: Use a straight edge or the board's own groove as a guide. Place all characters so their bases sit on the same invisible line. Checkpoint: view the board from a low angle; any character that floats or sinks will stand out. A consistent baseline makes mixed letters and numbers look deliberate.
- Mix letters and numbers sparingly: Limit yourself to one or two 50mm numbers per layout. Use smaller letters for the surrounding text so the numbers remain the accent. Common mistake: using numbers for every word, which flattens the hierarchy. If everything is large, nothing stands out.
- Photograph and adjust: Take a photo of the finished board on your phone, then look at it away from the wall. Photos reveal crowding and misalignment you miss in person. Checkpoint: if the photo looks busy, remove one element rather than adding more. The camera is a stricter editor than your eye.
- Refresh without rebuilding: When you change the message, keep the number in the same position and swap only the words around it. This preserves the board's visual anchor and saves time. Common mistake: redesigning the whole layout every week and losing the rhythm you established. A fixed anchor makes future layouts faster and more consistent.
