+I need to calculate the length when rendered of a lot of strings using a custom font.
+Can you use label: and let ImageMagick calculate the width needed for you?
+<code>
+convert -font "Arial" -pointsize 64 label:"this is the text" out.png
+identify out.png
+out.png PNG 396x73 396x73+0+0 8-bit sRGB 256c 2.57KB 0.000u 0:00.000
+</code>
+or, more simply:
+<code>
+convert -font "Arial" -pointsize 64 label:"this is the text" -format %w info:
+</code>
+or, as Eric suggested:
+<code>
+convert -font "Arial" -pointsize 64 label:"this is the text" -format %w +identify result.png
+</code>
+Or, if you want to use annotate, you can make a larger canvas and trim it, like this:
+<code>
+convert -gravity west xc:white[1000x1000] -font "arial" -pointsize 32 -annotate 0 "this is the text" -trim -format %w info:
+</code>
