Tutorial: Station Labels Using the “Core Type Area” - Part 2: 45-Degree Angled Route Lines
Following on from last week’s tutorial, here’s how to use the Core Type Area to make your station labels align perfectly and consistently when you’re applying them to 45-degree angled route lines.
If you use the edges of the Core Type Area when you’re aligning labels to horizontal and vertical route lines, then it should make perfect sense that you use the corners of it when you’re labelling angled stations. The first GIF shows the defining setup — using the bottom right corner for labels above and to the left of the route line and the top left corner for labels below and to the right of the route line. I’ve shown this setup first because it always looks right: there’s always a capital letter in the former, and the bottom right edge of a lower-case letter in the latter.
The second image shows what happens when you apply the same rules to the opposite angle. That is, using the top right corner for names to the left and below the route line, and the bottom left corner for names above and to the right. When the route line is angled like this, it can be harder to see that you’ve got the placement right, because the letterforms are more varied.
In the first instance, the last letter of a word could be an “n” (as we have here) or a “d”. We need to allow space for the “d” to fit comfortably, hence the use of the Core Type Area, which shows us exactly that. Whatever you do, don’t nudge labels without a final ascender up until that letter aligns with the station marker: this is what leads to uneven and inconsistent baselines as seen on the recent Sydney Trains map redesign.
Labels to the right and above aren’t quite as bad, but there’s still some variance: the first letter could be a “T”, “B”, or “W”, all of which have a different visual relationship to that bottom left corner. Remember to use the Core Type Area — the box that defines the maximum size the label could take up — and not the letterforms themselves to align text to markers and you should always be okay.
The last image shows a mistake I see quite often when designers try to align their labels to 45-degree lines by simply moving the label sideways from the marker, instead of across and up/down an even amount. I personally prefer not to do this, as I think it creates uneven spacing, but it can look effective and interesting when done right.
However, be aware that labels that sit on the lower side of the route line need to hang from the top of the Core Type Area (by their cap height) or they’ll end up being too close to the route line, as shown in the image. Type that sits on the higher side of the route line can sit on its baseline.
