Blank VHS tapes come in different lengths, indicated by numbers like T-120 or T-160. Understanding these designations helps you choose the right tape for your needs.
The T-Number System
The number indicates recording time in minutes at SP (Standard Play) speed.
Common lengths:
T-60: 60 minutes SP / 120 minutes LP / 180 minutes EP
T-90: 90 minutes SP / 180 minutes LP / 270 minutes EP
T-120: 120 minutes SP / 240 minutes LP / 360 minutes EP (most common)
T-160: 160 minutes SP / 320 minutes LP / 480 minutes EP
T-180: 180 minutes SP / 360 minutes LP / 540 minutes EP
T-120: The Standard
T-120 became the standard length because 2 hours at SP matches most movie lengths and provides convenient recording options:
• 2 hours at best quality (SP)
• 4 hours at good quality (LP)
• 6 hours at acceptable quality (EP)
Longer Tapes: Tradeoffs
T-160 and T-180 tapes use thinner tape to fit more length. This creates potential issues:
• More prone to stretching
• Can jam in some VCRs
• May not track as reliably
• More susceptible to damage
For important recordings, T-120 is the safest choice.
E-Numbered Tapes
In Europe, tapes used E-numbers based on PAL timing:
• E-180 = 180 minutes at SP (PAL)
• E-240 = 240 minutes at SP (PAL)
These don't directly convert to NTSC times.
Blank Tapes Today
New blank VHS tapes are still manufactured, primarily T-120s. Expect to pay $3-8 per tape. Previously recorded tapes can be re-recorded if the record-protect tab is present.
