Context : It is well known that the bright and remote Galactic globular cluster NGC 2419 has a very peculiar structure .
In particular its half-light radius is significantly larger than that of ordinary globular clusters of similar luminosity , being as large as that of the brightest nuclei of dwarf elliptical galaxies .

Aims : In this context it is particularly worth to check the reliability of the existing surface brightness profiles for this cluster and of the available estimates of its structural parameters .

Methods : Combining different datasets I derive the surface brightness profile going from the cluster center out to \simeq 480 \arcsec , i.e . \simeq 25 core radii ( r _ { c } ) .
The profile of the innermost 21 \arcsec has been obtained from aperture photometry from four different Hubble Space Telescope ACS/WFC images .
Outside of this radius , the profile has been obtained from star counts .

Results : The newly obtained surface brightness profile is in excellent agreement with that provided by Trager , King & Djorgovski for r \ga 4 \arcsec .
The new profile is best fitted by a King model having r _ { c } = 0.32 \arcmin ( \sim 5 % smaller than previous estimates ) , central surface brightness \mu _ { V } ( 0 ) = 19.55 and concentration C = 1.35 .
Also new independent estimates of the total integrated V magnitude ( V _ { t } = 10.47 \pm 0.07 ) and of the half-light radius ( r _ { h } = 0.96 \arcmin \pm 0.2 \arcmin ) have been obtained .
The average ellipticity in the range 5 \arcsec \leq r \leq 120 \arcsec is \langle \epsilon \rangle = 0.19 \pm 0.14 .
If the four points of the ellipticity profile that deviates more than 2 \sigma from the overall mean are excluded , \langle \epsilon \rangle = 0.14 \pm 0.07 is obtained .

Conclusions : The structure of NGC2419 is now reliably constrained by ( at least ) two fully independent observational profiles that are in good agreement one with the other .
Also the overall agreement between structural parameters independently obtained by different authors is quite satisfying .
