Los tamaños de los recursos de TikTok parecen simples pero se complican rápido: video, foto de perfil, anuncio in-feed, anuncio top-view, efecto de marca, portada de anuncio, banner de hashtag patrocinado. Si subes algo con las dimensiones equivocadas, TikTok recorta automáticamente contenido importante o rechaza el archivo. Esta guía documenta todas las especificaciones de tamaño actuales de TikTok; el redimensionador gratuito de abajo convierte cualquier imagen o fotograma de video a las dimensiones correctas en un clic. Sin registro, sin marca de agua.
TikTok video size: 1080×1920 (9:16)
TikTok videos use **1080×1920 pixels** at a **9:16 vertical aspect ratio**. This is non-negotiable — uploads at other ratios get auto-cropped with black bars or pillar-boxed, killing engagement on the For You page.
**Length**: 3 seconds to 10 minutes (longer for some accounts).
**Format**: MP4 or MOV.
**File size**: under 287 MB on mobile, 500 MB on desktop.
**Frame rate**: 30 fps standard, 60 fps supported.
Design rule: TikTok's UI overlay (username, caption, sound info) covers the bottom 20% of the screen. Keep key text and CTAs in the top 60% — middle of frame works best.
TikTok profile picture size
**200×200 pixels** displayed; upload at 800×800 for retina display sharpness. Aspect ratio: 1:1 square (displays as circle).
File formats: JPG, PNG. Under 5 MB. Animated profile pics not supported.
Design rule: profile pic displays as a circle in TikTok's UI — design assuming circle crop. Center the subject; leave margin around the edges. Single faces, simple logos, and bold single-color brand marks work best at the displayed 40×40 px size in feeds.
TikTok ad sizes (TikTok Ads Manager)
**In-Feed Ad video** — 1080×1920 (9:16) or 720×1280 minimum. Same as organic.
**TopView Ad video** — full-screen 1080×1920. Auto-plays with sound when app opens.
**Brand Takeover (static image)** — 1080×1920 px, JPG or PNG.
**Brand Effect (sticker)** — varies by effect type; check TikTok Creative Center for current specs.
**Branded Hashtag Challenge banner** — 1080×1920.
All ad assets use the same 9:16 vertical ratio as organic content. The advantage of pre-resizing: ad files often face stricter quality review than organic, so getting dimensions exactly right reduces rejection cycles.
TikTok thumbnail (cover) size
TikTok automatically picks a thumbnail from your video, but creators can override via 'Select cover' during upload. Custom cover size: **1080×1920 pixels** (same as the video frame).
If you upload a separate static cover image, use 1080×1920 and design it as a feed-grid hook — what shows on your profile grid (3-column display) is the cover. Strong covers consistently lift profile-to-follow conversion rates 15-25%.
Why TikTok asset specs matter more than other platforms
TikTok's For You algorithm uses watch time as the dominant ranking signal. Anything that hurts watch time — wrong aspect ratio causing letterbox bars, low-resolution upload triggering compression blur, mismatched cover that misrepresents the video — drops your reach hard.
Upload at 1080×1920 native, never below. Don't trust TikTok's auto-resize. Pre-resize once with the tool above; reuse the framing template for every video.
