# An elaborate 'fancy' header (book design)

I wish to design a book with the following style of header

The pages are to be set on A4paper with a margin of about 1 inch. I am currently using the code

     \usepackage[margin=1in]{geometry}


for margins, but I'm unsure as to whether there is a more effective option available. To achive the bullet between 'Chapter 1' and 'A chapter' I am planning on using the code

     \tikzcircle[fill=...]{3pt}


(the dots to represent the light blue colour shown in the mock-up picture). The document class will obviously be book with 12pt font, which I have chosen to be mathptmx. However, as someone who is only a beginner on Latex, I was wondering if anyone could provide a code which produces headers as shown in the mock-up. Fancyhdr seems to be the way forward and is the most versatile tool, but the fading circles seem to be the most difficult to replicate (I've had no success at recreating these so far). If anyone could help recreate the image I'd be very grateful.

• I think A4 paper with 1 inch margin probably makes the text too wide. Such wide lines generally make reading uncomfortable. – Piet van Oostrum Nov 29 '16 at 15:27
• Ah ok. What sort of margin do you think will look better? – wrb98 Nov 29 '16 at 15:28
• Usually the text width should be on average something like 60-70 characters. I woul like to advise you to read the documentation of the memoir documentclass. Especially section 2 has some excellent information about page design. – Piet van Oostrum Nov 29 '16 at 15:33
• \usepackage[a4paper, margin=4cm, headheight=23pt]{geometry} looks better to me. I have now put that in my code. – Piet van Oostrum Nov 29 '16 at 15:38

• That seems to work OK, however it seems that the Chapter 1 Test Chapter and the number in the blue circle are not aligned properly. Could you suggest a fix? – wrb98 Nov 29 '16 at 15:34
• We have to specify  anchor=base for the circles. But then the empty circles must have some contents that defines the baseline. I have updated the code. – Piet van Oostrum Nov 29 '16 at 15:52
