! Standar !! Kelas !! Resolusi !! Piksel!! Rasio Aspek !! Catatan
|-
| MMS-Small || 96p || 128×96
|{{Multiply|128|96}}|| 4:3 || Ukuran terendah disarankan untuk digunakan dengan video [[3GPP]] yang dikirim melalui [[MMS]] ke/dari [[telepon seluler]], resolusi yang cocok dengan layar telepon seluler berwarna terkecil yang umum digunakan.
|-
| QQVGA || 120p || 160×120
|{{Multiply|160|120}}|| 4:3 || Digunakan dengan beberapa [[webcam]] dan [[ponsel layar warna]] awal, biasanya digunakan di [[komputer]] [[desktop]] awal dan [[aplikasi]] [[video]] [[online]]. Resolusi video terendah yang biasa digunakan.
|-
| QCIF Webcam || 144p || 176×144
|{{Multiply|176|144}}|| 11:9 || Sekitar seperenam resolusi [[PAL]] [[analog]] (setengah [[horizontal]], sepertiga [[vertikal]]). Juga ukuran yang direkomendasikan untuk video [[MMS]] kualitas "sedang".
|-
| YouTube 144p || 144p || 256×144
|{{Multiply|256|144}}|| 16:9 || Sepersepuluh dari 1440p. Resolusi terendah di YouTube.

| NTSC square pixel || 240p || 320×240
|{{Multiply|320|240}}|| 4:3 || Sebanding dengan output "resolusi rendah" dari banyak komputer rumahan dan konsol game populer, termasuk VGA "Mode X". Digunakan dalam beberapa webcam dan untuk perekaman video di kamera digital awal dan telepon kamera, dan layar [[ponsel pintar]] kelas bawah. Resolusi YouTube asli. Ukuran maksimum yang disarankan untuk video [[MMS]] "besar".
|-
| [[Common Intermediate Format|SIF (525)]] || 240p || 352×240
|{{Multiply|352|240}}|| 4:3 || VCD / DVD putar super panjang standar [[NTSC]]. Piksel kecil / tinggi.
|-
| NTSC widescreen || 240p || 426×240
|{{Multiply|426|240}}|| 16:9 || Sama seperti mode "240p" YouTube saat ini; resolusi layar dari beberapa pemutar DVD portabel anggaran. Resolusi NTSC penuh sekitar sepertiga (setengah vertikal, dua pertiga horizontal).
|-
| [[Common Intermediate Format|CIF]], SIF (625) || 288p || rowspan="2" |480×272
| rowspan="2" |{{Multiply|480|272}}|| 4:3 || PAL-standard VCD / super-long-play DVD. Wide/short pixels. Also a common resolution in early webcam / video conferencing, and in advanced featurephones and smartphones of mid-2000s (''ca'' 2006).
|-
| [[PlayStation Portable|PSP]] || 288p || 30:17 || Notionally 16:9 with slight left/right edge cropping. Used in many portable DVD player screens and other small-format devices besides.
|-
| 360p || 360p || 480×360
|{{Multiply|480|360}}|| 4:3 || Uncommon, used in some lower-mid-market smartphone screens and as an intermediate screen resolution for some 1990s videogames.
|-
| Wide 360p || 360p || 640×360
|{{Multiply|640|360|nosep=}}|| 16:9 || Current base resolution in YouTube, labelled as "360p".
* The lowest and least computationally demanding resolution supported by hardware able to run mainstream desktop operating systems;{{vague|date=April 2016}} the lowest interruption-free resolution with low-end broadband connections.
* Typically used as the base "SD" standard by [[Video on demand|VoD]] services due to subjective similarity (and similar pixel counts) to a mid-grade free-to-air broadcast picture.
* Effectively, the resolution offered by any higher-definition 16:9 video scaled down for a standard 640×480 (VGA) computer screen. Offers 75% of the pixel count of a true anamorphic NTSC DVD image, or 89% of a letterboxed 16:9 image.
* Historically used as an ad-hoc standard for intermediate-quality / CD-R-sized MPEG4 conversions on P2P file sharing networks.
