I know this is a very old question  but from twig 1 6 you can use the slice filter      myentity text slice 0  50               The second part from the tilde is optional for if you want to add something for example the ellipsis   Edit  My bad  I see the most up-voted answer do make use of the slice filter

An even more elegant solution is to limit the text by the number of words  and not by number of characters   This prevents ugly tear throughs  e g   Stackov        Here s an example where I shorten only text blocks longer than 10 words      set text   myentity text  split              if text length  gt  10            for t in text slice 0  10                t            endfor               else           text join            endif

Update for Twig 2 and Twig 3   truncate filter is not available  instead of it you may use u-filter  here is an example       Lorem ipsum  u truncate 8     Lorem ip      Lorem ipsum  u truncate 8            Lorem      Note  this filter is part of StringExtension that can be required by   twig string-extra

Use the truncate filter to cut off a string after limit is reached      Hello World   truncate 5        default separator is          Hello      You can also tell truncate to preserve whole words by setting the second parameter to true  If the last Word is on the the separator  truncate will print out the whole Word        Hello World   truncate 7  true        preserve words      Here Hello World    If you want to change the separator  just set the third parameter to your desired separator       Hello World   truncate 7  false                 Hello W

mshobnr    olegkhuss solution made into a simple macro      macro trunc txt  len  -          txt length  gt  len   txt slice 0  len            txt      - endmacro      Usage example      tools trunc  This is the text to truncate     50       N b  I import a Twig template containing macros and import it as  tools  like this  Symfony       import   AppBundle tools html twig  as tools -     Also  I replaced the html character code with the actual character  this should be no problem when using UTF-8 as the file encoding  This way you don t have to use  raw  as it could cause a security issue
