Tolerants (Inglise keeles: dimension tolerance, tolerance) on masinaehituses mõõtme lubatav kõikumise ulatus ehk piirmõõtmete ehk piirhälvete vahe. Tolerants on alati positiivne suurus (märgita, mitteskalaarne). Teda võib tõlgendada ka kui täpsuse määra.
Kui kujutada suurimat ja vähimat piirmõõdet kontsentriliste ringidena, siis detail loetakse kõlbulikuks, kui tema tegelik mõõde asub piirmõõtmete (nende ringide) vahel. Kummalegi poole jääb pool tolerantsi.
Võtame näiteks mõõdu 35-0,2+0,3. Sellisel juhul on mõõtme lubatav kõikumise ulatus 0,5 mm (|-0,2|+|0,3|=0,5).
Tolerantsid μm- tes mõõtmetele kuni 500 mm
