  The size of the particle emission region in high-energy collisions can be
deduced using the femtoscopic correlations of particle pairs at low relative
momentum. Such correlations arise due to quantum statistics and Coulomb and
strong final state interactions. In this paper, results are presented from
femtoscopic analyses of $\pi^{\pm}\pi^{\pm}$, ${\rm K}^{\pm}{\rm K}^{\pm}$,
${\rm K}^{0}_S{\rm K}^{0}_S$, ${\rm pp}$, and ${\rm \overline{p}}{\rm
\overline{p}}$ correlations from Pb-Pb collisions at $\sqrt{s_{\mathrm
{NN}}}=2.76$ TeV by the ALICE experiment at the LHC. One-dimensional radii of
the system are extracted from correlation functions in terms of the invariant
momentum difference of the pair. The comparison of the measured radii with the
predictions from a hydrokinetic model is discussed. The pion and kaon source
radii display a monotonic decrease with increasing average pair transverse mass
$m_{\rm T}$ which is consistent with hydrodynamic model predictions for central
collisions. The kaon and proton source sizes can be reasonably described by
approximate $m_{\rm T}$-scaling.
