Objects often can't take all the text that you want to fit into it at the font size you want it to be, even after the inset margin is set to zero. This problem occurs often with nonrectangular objects - ovals, stars etc.
One way of going round this problem which I've been successfully using is to superimpose a separate Text Box over the Object (shape):
- format the Object (rectangular, oval, star etc.) the way you want it to look;
- create a floating text box, set wrap to none, make frame invisible, set dimensions to be equal or slightly bigger than the object, type in your text, format it the way you want it to look 'inside' the object;
- move text box over the oval (use 'Bring to front' under Arrange menu if the Text Box slides under the shape);
- Group the object and the text box together or 'Print' to PDF if it is to be used later as a repeating feature, like, for instance, an ad booked for a long series.
That way you can 'fit' much more text with letters almost touching the edges of the object which is not possbile if you try just to type inside it.
This simple trick could also be used for attractive design purposes, when letters inside an colour-filled object touch or even 'poke through' the frame of an object.
This method is similar to the 'patchwork' tehcnique of making quick-fix corrections in ready supplied images and text files in PDF format. Please check this earlier article:
