To elaborate:
(1) You first have to calculate the maximum permissible pixel height of
the echo area window from the character height of the frame where
you intend to display the completions and the value of
`max-mini-window-height' height as specified for that frame. Note
that for a minibuffer-less frame the echo area window may appear on
another frame whose character height you have to use here.
(2) You then have to calculate the pixel height of each completion line
as if it were shown in the echo area window mentioned in (1) using
`window-text-pixel-size' and add it to some cumulative height until
you have exhausted the maximum permissible height calculated in (1).
