It counts the number of characters in a string up until it finds the "NULL" end of string marker.
Serial.println(strlen(t));

Thanks @VE7JRO, it does the job :)
const byte bufferSize = 16;
char inputBuffer[bufferSize + 1];
int myDelay = 20;
void setup(){
Serial.begin(9600);
pinMode(13, OUTPUT);
pinMode(12, OUTPUT);
}
void loop(){
if(Serial.available() > 0){
byte bytesRead = Serial.readBytesUntil('\n', inputBuffer, bufferSize);
if(bytesRead == 16){
for(...

If you are able to send the message as 16 chars, followed by a newline, then here is a test sketch that might work for you. Use the Serial Monitor to send the 1000100100110101 data. Please ensure you have the Serial Monitor set to send a Newline Only.
// Valid input data from serial is 16 chars followed by a newline.
// 1000100100110101
