Infantil Size Photo: Mexico's 2.5 × 3 cm Tamaño Infantil

Infantil size photo dimensions

A tamaño infantil photo is commonly 2.5 cm wide by 3 cm tall (25 × 30 mm, about 1 × 1.2 in). We found no national rule that defines it; each institution publishes its own. One official example is Mexico City's SECTEI certificate procedure, whose diagram shows 2.5 cm across and 3 cm down, with 2 cm from the top edge to the chin and 1 cm below it.

At 300 dpi, 2.5 × 3 cm is 295 × 354 pixels, the size this page saves. If your instructions give another measurement, pick Custom size and enter it.

What institutions ask for besides size

Size is only part of it. SECTEI asks for a studio photo in black and white, retouched, on matte photo paper with a white background, and does not accept rounded corners. IPN's CECyT 19 wants colour on white, taken in a studio and printed on matte paper, and states «NO UTILIZAR FOTOGRAFÍAS DE CELULAR» (do not use mobile-phone photos).

Read your own instructions before printing. This page sets size, framing and background. It does not convert a photo to black and white or choose the paper, and the institution decides whether to accept a photo.

Other Mexican photo sizes

Infantil is one of several named sizes. The University of Guadalajara (CUCSur) describes tamaño credencial as 3.5 cm wide by 5 cm tall and tamaño título as 9 cm tall by 6 cm wide. For a Mexican visa, a 2025 requirements sheet from the Consulate General of Mexico in Houston asks for a passport-size photo with «Medidas: 39mm x 31mm». A Mexican passport needs no photo from you: the Consulate General in New York says a digital photo is taken inside the consulate.

Credencial and título measurements can be typed into Custom size, and the Mexican visa size is in the list under Mexico. The 35 × 45 mm passport size photo has its own page.

Printing at true size

The sheet is saved at 4 × 6 in (10 × 15 cm) and 300 dpi. Ask the lab for 100% scale with no fit-to-page so every copy measures 2.5 × 3 cm, then cut along the grey lines.
